    This is certainly an interesting development and our users will agree that the more aftermarket options they have the better. Evolution of Speed, who we have never heard of previously and have no affiliation with, is set to release their N5X intake manifold which will gain a lot of interest from N54 and likely N55 owners as well. The obvious here is that guys would want to pair this with methanol injection or port injection for supplemental fuel. The expected price point and design makes that aspect attractive. This would not be something that N54 or N55 owners expecting big gains over the OEM manifold would benefit from but for more hardcore owners making big power with say a single turbo upgrade. Exactly the kind of power junkies who are on BimmerBoost. It will be interesting to see the results from members who buy this product and what the options will be such as the finishes, integrated port injection, etc.

    The more I read about the GT350R the more enticing it becomes. Now, the Stingray is lighter and arguably sexier but the GT350R just has that special something. The flat-plane crank, the high revving V8, the carbon fiber wheels, the track focus, etc., it's like a better M3. Not to mention it is manual only making it a true driver's car as if the options to delete things like the navigation, AC, and rear seats didn't already tell you that. I'm in love with both of these cars:

    This is something we are going to see more of as the new M3 and M4 battle with the 335i and 135i models equipped with the N54 (with N55's more and more getting into the mix as well). This goes down about as one would expect with the F80 M3 pulling up top. The M3 has the advantage of the DCT transmission. The Eurocharged ECU flash tune with downpipes as this M3 has boosts things considerably. Basically, a bolt on F80 M3 should make a bit more power than a bolt on E9X 335i N54 but the N54 has some additional tricks up its sleeve that this particular example is not running including inlets and E85. This particular N54 is running meth injection though and the F80 M3 S55 is not which is a factor although it is on race gas. Ultimately, these are both 3.0 liter twin turbo direct injected BMW inline-6 motors and which is faster comes down to the amount of mods and really money spent. The M3 will ultimately have the advantages of the DCT transmission and the higher redline. It also is the more complete package to begin with. It's a bit of a shame these are chase view runs on the video (it should be a crime really) but it goes to show how quick a tune and downpipes M3/M4 is and how it stacks up to a bolt on N54.

    An interesting photo was posted from a BMW technical document on the BimmerBoost forums that gives a quick and easy overlay of the BMW N54 and N55 valvetrains including their VANOS camshaft adjustment ranges. The N54 and N55 of course are similar turbocharged and direct injected inline-6 motors sharing the same bore and stroke. They clearly are tuned a bit differently (due to the N55 being single turbo for one) and the N55's addition of Valvetronic plays a role. The N55 has a wider range of intake and exhaust VANOS adjustment as well as larger intake valve lift and cam duration compared to the N54 as the tech document highlights. Potentially the N55 can breathe better up top namely with a large turbo upgrade although tuning VANOS as well as Valvetronic is complicated. VANOS alone is a difficult system to tune and we have yet to see aftermarket VANOS cams working for the N54 or N55 motors. An interesting comparison nonetheless.

    Some tuners make big claims before a product is actually ready for prime time. You see it all the time on the forums and the hype builds to the point it is a runaway train. Responsible tuners temper these expectations by telling a potential customer it is not ready and some just act like it is ready to continue the illusion of product superiority. It truly is fascinating and interesting how some of these companies leverage forums to not just sell products but buy minds. The idea is controlling what people think by getting them to parrot back the same lines over and over. The danger with ESS-Tuning that a person who goes by by the name RingMeister01 found out the hard way is that they long ago bought and paid for the E9X M3 upgrade market by convincing everyone on the BMW forums they are the best based on sales volume. In turn, their fanboys outnumber the rest. This somehow has been perverted into BMW tuning superiority on every BMW platform that graces the earth. ESS-Tuning may sell a lot of superchargers (the reasons for that we will not go into here) but that does not mean they are a turbo builder. Far from it as a matter of fact. AMS found this out on their own when they dropped ESS-Tuning from their F10 M5 S63TU turbo upgrade project and ESS-Tuning was supposed to provide just the tuning there and not even the turbo hardware. AMS Performance deciding to tune on their own tells you plenty regarding ESS BMW tuning and turbo expertise. The simple fact is they don't have any and when AMS sought them out to tune they had no way to actually tune the ECU. It was BS. They source their turbo hardware from turbo builders but we do not know exactly which ones or if they are reliable. ESS-Tuning does not produce turbochargers themselves just as they do not produce superchargers themselves. They sell a complete 'kit' so to speak and this kit is what RingMeister01 thought he was getting. The problem is it was portrayed to him as ready to go and complete. Based on his experience, it was far from that. After the fact our favorite forum spinmeister Roman@ESS-Tuning stated it was not a complete product but a beta product and Mr. RingMeister01 should have known better: Clever, right? State the product is in beta and that the customer expectations are way out of proportion and he should not expect some complete product. It makes you wonder then why he was under the impression he was getting a complete product ready to go from ESS-Tuning. Is RingMeister01 just unreasonable? Perhaps he's just stupid? Or perhaps the product was misrepresented? Here is what RingMesiter01 thinks: "As if I had time for non-sense but I wouldn't want others to go through this as I did. I initially spoke to Jesse from Pure turbos on getting their kit but as he knows I didn't want to run a JB4 with boost juice to reliable make gains. I wanted a flash tune/turbo package. Jesse was very helpful in educating me on what they were offering and what to expect from their kit. I must say he is extremely knowledgeable and professional. IND working on their S63tu turbo upgrade with AMS was another option. Again this was in its early stages but I sent over a new set of turbos for them to look at for machining, etc. AMS at the time was so busy with whatever other monsters they are creating that they couldn't commit to a lead-time on developing the hardware for our cars. Ilia's plan was for AMS to upgrade the hardware and develop the tune with my turbos on IND's shop car. IMG Motorsports informs me that ESS has a kit ready to go, tune and all. He asks me to get my turbos back from AMS and send them to him for the ESS upgrade if I was interested. Like anyone else here, say ESS and its a no brainer (mainly from their success with the superchargers). The turbos are sent to IMG. I now email AJ for the upgrade details; In the email he clearly states that the kit is ready and the tune I would be getting is specific to the turbos. He also promises that they will be the best solution available. No problems at all thus far and I was really getting excited to be apart of this first kit. I offered to post a review, dyno charts and pilot runs on the forum. AJ then said "We'll give you a really good deal if you would do that for us." A few weeks pass and no word on the turbos (ecu was removed and sent within this period), so I email AJ. "Your turbos are with IMG, they were returned three weeks ago. He definitely has them." -AJ Hmm? Why wasn't I told? I send out a text message to find the turbos had arrived and that I was informed but most likely didn't receive the text from IMG because he was at Lime Rock Park and "there's no reception there, bro." Clearly that was the case as I see posts from him on Instagram all weekend from the track. Anyway... who cares, right? "AJ charged my credit card for your turbos, could you go make a cash deposit in my account for $5,000 tomorrow?" Ok now I'm a tad uncomfortable. AJ and I had spoken about pilot runs, dynos, reviews for the kit on the forum and now I'm being charged retail for the kit and I always thought I'd pay ESS directly. I ask IMG why I was being charged retail when I had already been offered a discount, "cause everything else out there is junk, bro. This is what he charged my card." Ok, I understand IMG would not be aware of my conversations with AJ, so I email AJ directly on the spot. "Your pricing is determined by the vendor, we have nothing to do with that on our end. You must go through one of our vendors." WTF. That awful feeling in my stomach comes over and I realize that this isn't going to be what I signed up for. See now Im in no control what so ever and Im at the mercy of a vendor I don't feel comfortable with and I have no choice but to pay whatever he wants me to, to get my turbos back. I emailed AJ again and bitched until IMG sent me a text "Bro, AJ refunded my card $500." Ok, lets just move forward... The ECU comes back (I must had sent 10 emails asking whether the tune was specific to these turbos and if I could please have CEL, Vmax and cold start deletes, I was assured I would. I didn't want to have the ecu removed and installed multiple times due to the process) and everything comes together at which time I get a text from IMG "car is done, get ready for 550 whp, bro" EXCITED!!! I get to the techs place (who btw is so talented and genuine). I sit in the car and say to myself (knowing how irresponsible and nonchalant this "vendor" is) I fucking bet it goes through cold start. Hit the starter button and of course, its there. I'm sure Vmax isnt deleted either. So lets just drive and see how she performs. Very smooth operation at low speed driving through a residential neighborhood, like stock. The turbos are a little loader but that is probably due to downpipes and BMC filters. I make my way to the highway and WOT. More lag and not much else. Doesn't feel fast or powerful at all. I have been in a lot of M3/4's with ecu flashes and JB4's and this just didn't impress me. I text IMG on my feed back, "Bro, put some good gas in and let it adapt. It takes 80 miles to do so. The set up is so smooth its deceiving." EEERRR....really? A day or two pass and I see this thread and comment that this kit isnt all that. I have every right to post an honest option and review, I always do and without any agenda or with any intention of hurting someone. I always valued the opinion of the members here and considered their experiences when purchasing a product. I wanted to do the same. This is when the truth unfolded. I get a message from Roman, "You aren't allowed to comment on a development project until its completed." Development project? What? Back and forth with Roman I find out that my brand new M4 with 250 miles is a guinea pig for ESS' S55 turbo upgrade. Not a fully develop system as promised but something they were trying to test out. Now I'm furious and text and email all parties. Roman says to me "IMG and Aj said you were aware of this." Motherfookers. Im texting back and forth and clearly I'm upset and Roman offers to refund me and IMG offers to remove turbos put in stock set and refresh car to stock as long as I delete all posts on this thread. I deleted what I could on the spot and emailed Jason (admin) to remove/clean up anything else. Only a few minutes turned and Roman sends me a lengthily message on how I did recieve what i payed for; upgraded ecu and turbo kit and at a significant discount... $500.. really? If I cooperate I'd get free tune upgrades and if not then ESS will sever all ties with me and stop communication. I send him a text back..."You are so fucked" I did try to suppress my disappointment and the distrust I felt and continue to just get this kit to work. IMG takes my car to the dyno and puts down what you see on the thread BUT when I asked about the dyno and a picture of the dyno, I got a half ass cell phone pic of a 1/4 of the graph and blurry to the point it was hard to make out the numbers. I asked and asked for a full picture so I could see the curves and the crossing point...ect. I just wanted to stay on top of this if I was going to use my car for development. On and on and on I get a dyno file in a format I have no idea to do with (i guess its the dynojet software) wtf am I supposed to do with that? At the end I asked about the new tune I was getting and what was different about it from the Beta file I have now. I was concerned that they were just going to crank up the boost to make numbers on the dyno. I was then insulted by IMG through texts and I just called it quits. I just don't care anymore, $4000 for new turbos, $4500 for the upgrade, $1800 for tune and priceless lies. I would had been fine with everything but just don't lie to me and twist things to make me look stupid. Judge me I don't care, I have nothing else to share here. This is for anyone as a warning- know who you are dealing with, know what you are getting into because if it goes wrong you will be left for dead." This sounds like a guy who thought he was getting a product that works. ESS stating after all of this on the forums it was a 'development project' is obviously to affect public perception of the gigantic mistake of selling a product that isn't ready. Yes, ESS never told him that and told him the exact opposite according to his own words and the e-mail records. Apparently he has the e-mails showing this and I'm sure we would all love to see them but thus far he has not published them. If it were BimmerBoost, we would and we actually have to expose deception. Hopefully ESS doesn't push him around but he seems like a guy so far that isn't responding well to ESS demands. This guy thought he would be getting turbos and a discount to post reviews, dynos, runs, etc., on the forum. A pretty standard marketing practice on forums to get supposedly 'independent' reviews. Unfortunately, a certain ESS cheerleader serving as the middle-man here decided to charge full retail. Why? To line his own pockets of course. Who cares if it works, right? Well, reputable vendors care. Nobody cared here. Get the money and oh well too bad say it's 'beta' if it doesn't work. ESS tried to keep this off the forums but it didn't work: "This is when the truth unfolded. I get a message from Roman, "You aren't allowed to comment on a development project until its completed." Development project? What? Back and forth with Roman I find out that my brand new M4 with 250 miles is a guinea pig for ESS' S55 turbo upgrade. Not a fully develop system as promised but something they were trying to test out. Now I'm furious and text and email all parties. Roman says to me "IMG and Aj said you were aware of this." Motherfookers." RingMeister01 has every reason to be angry. Not only did he not get what he paid for, not only did he pay more than he was supposed to, he is now supposed to shut up about the problems. He finally realizes he is a guinea pig. It's just that he never signed up to be one. It is somewhat interesting as well that Roman@ESS commands him not to speak. Do you see now how certain forums work now? Anything negative is kept off. If you do not shut your mouth you will not get further support. It's not about having the best products. It's about making people think that you do. That is why he was offered a refund and a return to stock if he deleted all his posts. You would think that offer would be on the table regardless as it should be instead of being conditional. This customer chose not to bend over but how many have bent over for ESS? How much has been swept under the rug? BimmerBoost is aware of much of it and some of what gets deleted is hosted here for specifically this reason. You as a potential customer deserve to know the truth, don't you? You are not a vendor's pawn, are you? Shouldn't the customers have the power in this relationship? This is the same old story with ESS-Tuning as always but trying to get it out there is the problem. They use their power to pull posts, edit threads, close threads, etc., if they are not portrayed in the best light. It's arrogance, pure and simple. What they should have done is make it a priority to fix the guys car (another tuner offered to fly out to fix it), provide what he paid for, and not charge him a dime for any of it. That would require them going out of pocket. It's simply the easier (cowardly) way out to get this all deleted, spin it, and go about business as usual. They won't be able to delete this though. If they try, the blowback will be bigger than it already is:

    The BMW F80 M3 is the worst of this trio? That is what MotorTrend thinks which is in stark contrast to Car and Driver who picks the M3 over the other two. Car and Driver also though the ATS-V belonged in last place whereas MotorTrend puts it in the middle and behind the comparison winner which is the new Mercedes-AMG C63 S. Here is how they stacked up: 3rd Place: BMW M3 It's cliché to say, but this is the best third-place finisher in Motor Trend history. C'est la vie. 2nd Place: Cadillac ATS-V
 This stud athlete is let down by its lack of powertrain refinement and sonic thrills. Cadillac has very little tweaking to do to get things right. 1st Place: Mercedes-Benz C63 S AMG 
 An iron fist in a velvet glove. Race mode transforms the beast into an iron fist in an iron glove. Lap times: Caddy ATS-V 1:31.43 C63 1:31.52 BMW M3 1:32.51 How the M3 finishes behind the other two on the track is a head scratcher. The M3 is a full second behind the other two? Huh? It is the lightest car with the best balance. At 3498 pounds it undercuts the ATS-V by 286 pounds and the C63 AMG S by 434 pounds. The C63 AMG S weight distribution is 54/46% front to back and the ATS-V is 52/48%. The M3 is stated to be 50/50 in this test. The ATS-V is not beating the M3 around the track based on power or being lighter. It is tested as the slowest of this trio which is in stark contrast to Car and Driver's absurdly fast numbers for the automatic ATS-V. MotorTrend previously tested the automatic ATS-V and got a 12.3 @ 114.6 out of in the 1/4 mile. Now in this comparison they get a 12.1 @ 116.2. Quicker and faster yet still nowhere near Car and Driver's ATS-V tester which now looks like a ringer. We can not make sense of the acceleration numbers for the ATS-V as they are all over the place but the M3 and C63 appear to be exactly where they should be. The C63 AMG S is shown to be the fastest of the trio yet it was the slowest in the Car and Driver test. Seriously, what the hell is going on? The acceleration numbers here at least do not look suspect as the C63 AMG S should be faster than the M3 which it is. The wild card is really the ATS-V but it is performing more like the early reports showing trap speeds in the 115 miles per hour range than the outlier of 122. A spread of over 7 miles per hour is at least a difference of 70 wheel horsepower. It is also interesting to note all three get to 100 in 8.8 seconds but the ATS-V seems to start to run out of steam above 100 miles per hour. Ok, enough about potential ringers and testing anomalies. The main thing here is the stunning last place finish for the M3. The ATS-V is said to feel sportier and the C63 AMG S is said to be the best all around package. How the lightest and best balanced car here loses and posts such a poor laptime we can not explain. The ATS-V posting the quickest laptime considering its figure eight advantage and best braking performance makes sense but the C63 beating the M3 here does not considering other track tests have shown the opposite.

    Motor Trend compars BMW M3 vs. Cadillac ATS-V Sedan vs. Mercedes-AMG C63 S ATS-V really shines in just about every performance measure. C63S takes home the win due to overall package, ATS-V lacking in refinement. BMW M3 takes third, but by no means does Motor Trend say it is a terrible car. The segment is just full of very capable machines. 3rd Place: BMW M3 It's cliché to say, but this is the best third-place finisher in Motor Trend history. C'est la vie. 2nd Place: Cadillac ATS-V

    Cobb's Porsche 991 Turbo tuning development continues and they are moving rapidly. Below are results for Cobb Stage I and Stage II OTS (off the shelf) tuning. These numbers are results anyone can expect with the OTS tunes and of course they can be further customized if one wishes. The torque gains massive with just the Stage I OTS tune on pump gas. They were able to pick up an additional 107 lb-ft of torque at the wheels. Stage II on pump gas takes this to 652 lb-ft of torque at the wheels for a gain of 120 lb-ft. The biggest horsepower gains come on race gas but that raises the question of diminishing returns due to cooling issues. PorscheBoost of course already explored 991 Turbo and Turbo S heat soak issues and Cobb is well aware of cooling limitations especially when tuning. Cobb is working on intercooler upgrades to overcome any limitations and push things forward. Impressive work thus far. Our Porsche Experts have been hard at work making sure we’re all set for the Porsche 991 Turbo Accessport release which is getting closer by the day! The most fun part of that process is strapping the cars down to the dyno and seeing just how much power they make after a bit of tuning. We were extremely lucky to be able to work with Porsche of Colorado Springs for the Pikes Peak International Hill Climb. That experience enabled us to learn a TON about these cars and how they react to different tuning strategies, aftermarket bolt-on parts, or differences in fuel quality. Below, we’ll take a look at some of the power gains we’ve seen. First, on an otherwise stock car followed by gains associated with an upgraded exhaust and appropriate tuning. As a note, the data in the graphs was recorded on two separate days however the delta from the baseline pulls remains accurate. Seen here is our initial Stock Baseline pull on 91 octane fuel along with a Stage 1 OTS map using 93 octane fuel. A Stage 1 map would be used on an otherwise completely stock vehicle. Power under the curve is significantly increased throughout the low and mid range. Maximum gains of around 60whp are seen between 3000-4000 RPM. Most impressive is the increase in low-end torque, with gains of over 100 ft/lbs! Next up, Stage 2. A Stage 2 map is calibrated to be used on a car with upgraded exhaust. As is evident with the power gains, the motor is able to flow a significantly greater amount of air with the freer flowing exhaust. With gains of 120 ft/lbs down low and nearly 100 hp at peak, the cars become a whole new animal. We are able to be a touch more aggressive utilizing 100 octane fuel, this will be a great option for customers interested in tracking their car where detonation resistance is key. Stay tuned as we continue development on this platform. At this point, the cars will really need an improved cooling system to make any additional power. We’re already in contact with top intercooler providers in the industry with intentions of overcoming the next bottleneck in power.

    Very impressive Stage 2 M178 tuning numbers here from Renntech. As you may recall, Renntech started work on the M178 motor early this year. They showed a baseline of 531 crank horsepower and 472 wheel horsepower. They have the AMG GT S with their turbo upgrade and downpipes up to 682 crank horsepower or 625 at the wheels on their dyno now. Those are some major gains. Torque alone is up by 167 lb-ft over stock. What is also nice to see is how flat the M178 torque curve is once the motor spools and how the torque curve does not really start to drop hard until past 6500 rpm. The M178 in general is definitely breathing better up top than the M177 in the C63 especially this example. Renntech previously shared an acceleration video of their intermediate tuned AMG GT S running up to 195 miles per hour and this time they take it to 199 miles per hour with the Stage 2 setup. The car accelerates hard with the Stage 2 package and the gearshifts look to be about instant. They get to 198 miles per hour in no time. It's incredible how easily the car gets there and with no drama whatsoever. This car is fast. It will be interesting to see how much further Renntech takes it on the turbo upgrade with race gas but for now they obviously are not pushing the transmission beyond its limits.

    The boys at MT stated the trans in the new C63 S is as good as PDK. I thought it still has same ole trans w older model?

    Ford held a press day for the upcoming GT350 and GT350R Mustang models at the 2.0 mile long Grattan Raceway in Michigan. Ford provided some key information on the GT350 and GT350R including that their curb weights are 3760 pounds and 3650 pounds respectively. Not light but not super heavy either. Oh, and how about the fact the GT350R beats the 911 GT3 by 1/10 of a second at this racetrack? That is the Ford press claim. Things may change on different days on different tracks but what it shows is that on the racetrack it is a driver's race between the GT350R and the 911 GT3. That is incredible considering the GT350R is less than half the price.

    The new CTS-V is finally getting into the hands of the magazines and Car and Driver is the first to publish their test figures. Now, before we delve into them we want to raise a bit of a red flag with Car and Driver's Cadillac results considering their major disparity in ATS-V testing. Is Car and Driver in bed with Cadillac? Is Cadillac sending tweaked press cars? Are the new Cadillac V models just spectacularly quick? Is it all of the above? Is it none? In all likelihood the CTS-V performs exactly as the numbers here show. We just want to point out that magazine numbers are harder to trust these days and to get the complete picture we need to see some independent results as well as a comparison with its competition for context. With that out of the way let's look at the figures for the 8L90 8-speed automatic equipped version. 0-60 in 3.6 which is highly impressive for a car with this level of torque and a positive displacement blower. 0-100 in 7.5. The 1/4 mile comes in 11.8 seconds at 124 miles per hour. It is essentially a lighter and faster M5. The CTS-V weighs 4129 pounds which puts it at roughly 250 pounds less than the BMW F10 M5 and roughly 450 pounds less than the Mercedes-AMG E63 S and Audi RS7. How about that, the Cadillac is the lightest of the bunch. Unfortunately Car and Driver did not provide a weight distribution figure but the Cadillac is likely balanced better than the nose heavy RS7 and E63. With grip in abundance as highlighted by .98g on the skidpad this car is going to be more playful than its rivals when hitting the turns. That is kind of the point. This thing can do more than just go fast in a straightline even though it should rule the highway compared to its German competition. The Cadillac is the lightest, likely the best handling, and also likely the autobahn king. Things sure are changing. Cadillac sure is pricing themselves like the Germans. The as tested figure of $95,290 is not cheap and certainly creeping up there. The CTS-V is offering German levels of refinement though, arguably better handling and performance, and is cheaper depending on how the cars are optioned out. It certainly is fair for Cadillac to price themselves the way they are considering what the vehicle offers. We will have to wait and see how it stacks up in direct comparisons but things are looking good thus far. The CTS-V is poised to be the cream of the luxury super sedan crop offering the best all around blend of price, performance, comfort, driver involvement, and luxury. Those traits used to be BMW's recipe for success.

    Improving on the factory BMW airbox design for the F80 M3 and F82 M4 is not easy. It is not like the BMW engineers do not design efficient parts themselves but they do have to work within a certain budget and with BMW suppliers as well as deal with strict regulations. As we all know there is room to improve on many BMW factory parts including something like the intake system on the S55 motor in the F80 M3 and F82 M4. Gains really show when someone is running a tune or higher boost as the factory system becomes more of a restriction at that point. Look at the dyno results on a Mustang dynamometer here from AWE-Tuning. The aftermarket part and the factory part perform about the same until the motor is past 3k rpm. At that point the S-Flo system provides greater flow on the test car which is running their piggyback tune and exhaust system. At the factory power levels gains will be minimal but this is a mod for that person trying to extract every last horse and remove restrictions. What the dyno results prove is that the factory intake can be made more efficient and this pays dividends as the motor is pushed harder. Is this system worth the $1595 they are asking for it? Well, that is up to you. For the cost conscious the recently released BMS system is quite the value alternative. The AWE piece sure is pretty though and offers OEM fit and finish.

    It has been a while since BMW introduced the M6 GT3 set to replace the Z4 GT3. BMW Motorsport director stated the 24 Hour Dubai and Daytona races in 2016 are what they are targeting, "That’s obviously what I think customers would like to run and that’s what we’re clearly aiming at." Those are big endurance races and certainly a good time to make a debut. They are also still a ways off which means testing can continue and the car should be ready to go next year. What BMW is doing is tweaking and testing the car for privateer teams, "That’s the focus of our development program is that we hand over a car to the customers that’s already developed, that not necessarily has raced in the hands of a works effort from our side. It’s competition. But as we’ve said before and I would like to stress again, this is really customer racing. Therefore, for us, it’s not an option to enter a prototype on a works level and compete against our customers or potential customers. This is customer racing and nothing but." Do not expect a factory backed effort with the M6 as you saw with the Z4 and M3 previously. As a reminder the M6 GT3 features a 500 horsepower 4.4 liter twin turbo V8 based on the S63TU engine design with a dry sump oiling system. The power is routed through a six speed sequential manual gearbox. With a dry weight of 2866 pounds it should move quite quickly.

    We spend most of our time on speed and power here but it never hurts to look good while going fast. This 6-Series certainly looks good with the Prior-Design F13 650i widebody kit. The fitment and paint all look to be very well done almost as if OEM. Which is interesting as we have members here who have purchased Prior-Design products only to report poor fitment. There certainly is likely a difference between the cars and parts used for marketing such as this and what customers actually get simply based on reports and results posted on this network. That said, this particular example of Prior-Design's work combined with wheels from Vossen certainly looks good. Brembo brakes and a GT Haus Meisterschaft exhaust help finish things off.
