    If you only disable traction control the ESP will be your safety net no matter what you do. Even on track days I normally leave this option on if the track is slightly damp or I spot cars with leak oil on track. That has prevented me from spinning off on various occasions while keeping things reasonably safe and fun, and still have an acceptable slide angle to still feel playful.

    Naturally aspirated that's a sizeable gain.

    I already have row boxes. The renntech boxes do provide substantial gains. Im not sure who but a couple of years ago some one did back to back testing At the strip and picked up .2 down the 1/4 and 2mph in trap! Thats a big gain.

    Mercedes-Benz decided that they need to bridge the gap between the C400 and the upcoming 2015 W205 C63 AMG. The new W205 AMG C-Class will offer something around 500 horsepower meaning that there is a lot of space between it and the 329 horsepower W205 C400. No word on what the torque figure rises to in the C450 but with 4Matic all wheel drive likely standard just like the C400 there should be no problem putting that power down. Now, should one really opt for the C450 considering the C400 has the same M276 DELA 30 turbocharged 3.0 liter V6? If the E63 AMG and E63 AMG S is to serve as precedent, no. The only difference in those models accounting for the increased output is software and even higher performance software is easily sourced through the aftermarket for far less money. The exact same trick Mercedes pulls with the E63 is likely happening here but until we get an official press release we will not know for sure. Source

    Thank you for the response. It appears that a Quaife will meet my requirements. I have experience similar events when the car has stepped out and I have corrected as the ESC/ESP has kicked in- safer and more predictable with it all turned off (for me having grown up on RWD cars).

    Many people have likely forgotten this but BMW did make high performance SUV's long before the X5M ever went on the market. Back with the first generation E53 X5 over a decade ago BMW produced the X5 4.8is model which was the highest performance X5 in all the land. With 355 horsepower and 360 lb-ft of torque from the 4.8 liter naturally aspirated N63 V8 it hustled the 5090 pound X5 to 60 in 6 seconds flat and through the 1/4 mile in 14.5 second at 96 miles per hour. How much have things changed in the decade since? The xDrive50i is not even the highest performance X5 available although until the new X5M hits it is the highest performance X5 available for the new F15 generation. It is roughly the equivalent in the model range of the X5 4.8is of a decade ago since an M model did not exist back then. In 2014 what this means is a 445 horsepower and 480 lb-ft twin turbo 4.4 liter N63TU twin turbo V8 powered 5306 pound monster that hustles to 60 in 4.3 seconds and through the 1/4 mile in 12.8 @ 109. To put it another way, quicker and faster than every M3 produced prior to the last generation E92 M3. You could line up next to an E39 M5 at a stoplight and pull away while sipping a latte. That is how fast BMW's SUV's have become but notice that they have not gotten any lighter. This generation was supposed to improve in that area by a couple hundred pounds (according to BMW who somehow keeps overstating their weight loss) but when weighed it turns out it actually isn't any lighter. Everyone will no doubt state this is very impressive acceleration and it is but there is one thing that old X5 4.8is did better than this new car. It went through the slalom quicker and pulled .83g on the skidpad to the 2014's .81g. It also stopped 5 feet shorter from 70 miles per hour. Hey, as long as this one is faster that is progress right?

    If you do not disable the traction control (only the first step is enough), in tricky situations the ESP can jolt the back around because the electronics counter reacts the LSD's input. You'll get used to that (strangely only happens on wet roads going uphill), or do as I do, and disable traction control and enjoy the LSD more (hail to the JB4 option which disables this for me automatically!). That will make the car a lot more predictable. I uderstand the reason for your last question, but for me the Quaife has never let me standing in slippery conditions In winter conditions I have winter tires so I never encountered a situation where I had no traction at all on one wheel. In fact having a LSD in snow is quite fun. And it is a moot point anyway, because if you ever find yourself on a tight uphill turn where one rear wheel is off the ground, you just make some friction to the wheel that's off the ground by pulling your handbrake slightly and you will get out of that sitiation with a Torsen diff. I would not worry about that at all. There has to be absolutely zero grip to even consider that trick. In 3.5 years with my Quaife it has never happened to me yet.

    By now you are well aware that Mercedes offers the 4Matic all wheel drive system for the facelifted CLS63 and E63 AMG models. So what happens when you put the pre-facelift rear wheel drive 63 AMG model up against the facelifted 4Matic all wheel drive model on the dragstrip? Even a casual automotive enthusiast would likely guess that the result would have the all wheel drive car showing the quicker ET (elapsed time) whereas the rear wheel drive car would have the higher trap speed. That is usually the case although by no means an automotive law. It is what happens in the drag race below though and that is partially due to both cars wearing street rubber. Soft drag rubber is pretty much a necessity for a high torque rear wheel drive vehicle to get good traction off the line at the strip. Now, this is not exactly apples to apples as the C218 CLS63 has an ECU tune. The W212 E63 AMG S is stock and an ECU tune makes a huge difference in power and torque. Combine an output increase as a result of ECU tuning for the CLS63 along with its roughly 200 pound lighter weight and it is no surprise it traps 128.72 miles per hour to the 4Matic E63 117.83. A difference of almost 11 miles per hour is huge and using the old rule of thumb of 1 mile per hour being equal to 10 wheel horsepower without even seeing the dyno numbers of the two cars we know the CLS63 is putting out roughly 100 more horsepower at the wheels. A trap speed is often as good as a dynograph. Even though the CLS63 is lighter and more powerful it still takes longer to cross the 1/4 mile mark at 12.190 seconds. The stock E63 AMS S 4Matic does it quicker with an 11.863. It should be clear how these two important parts of a 1/4 mile run each have their own particular variables yet they relate to each other. It still is amazing how many people make basic errors when referring to which car is faster (trap speed) or quicker (elapsed time) when talking about a slip and the variables that influence the result. This is about as simple and clear of an educational 1/4 mile run in relation to illustrating time and speed as there can be.
