    According to this chart:
    http://www.wavetrac.net/application_bmw335.htm

    You need the install kit: 30.309.171WK

    Which is:
    "Upon receipt of a customer’s differential/ring gear assembly, the ring gear is separated from the stock diff using CNC equipment. The ring gear is then machined, drilled and threaded to allow bolt mounting to a new WavetracŪ differential."

    Also - VAC offers this in Philadelphia.

    You might have a bolted ring gear the only way to find out is to open it up.

    Here's what I would replace:
    Basically the shaft seals have seals + new c-clips.
    2 33-10-7-505-605 SHAFT SEAL WITH $22.27
    1 33-10-7-609-536 SHAFT SEAL $31.27

    So here's some other parts that some people replace, but you don't need to:
    6 33-20-7-572-717 REINFORCEMENT $4.69
    12 33-20-7-572-716 TORX SCREW WITH $2.25
    10 33-13-2-227-347 HEXAGON ANTIFATIGUE $8.75

    Reinforcement and torx screws hold the axle to the half-shaft, BMW recommends replacing these, but you can loctite yours and be fine.

    The hexagon anti-fatigue bolts are recommended for replacement by some if you have a non-bolted/welded ring gear you'll get a set with your new bolted ring gear.

    BMW also indicates that the driveshaft nut should be replaced, I don't have the PN for that. This as well is unnecessary.

    Each input and output point on the diff has two dust covers, these can be carefully removed and re-installed:
    2 33-13-7-500-876 DUSTCOVER PLATE, $12.84
    2 33-13-7-500-877 DUSTCOVER PLATE, $11.54
    1 33-12-7-518-511 DUSTCOVER PLATE, $5.48
    1 33-12-1-214-064 DUSTCOVER PLATE, $11.20

    You can also bring the bearings in to a bearing shop for replacement, this is unnecessary.

    I just emailed Wavetrac to see what the process is for getting this installed, they are in Cali and if its pretty straight forward I will prob end up picking this up for the shop car, any quick things you can tell me about it compared to the Quaife?

    Both are Torsen-type LSDs.

    Wavetrac is less $, USA company, tension at zero load provides more lock when one wheel is airborn or on glare ice with no friction. <--this is really the only difference worth noting. However how much more lock is unknown...and this situation so almost never occur.

    Quaife has long history of reliability well known brand name, etc.

    There are a ton of threads comparing them online.

    Oh and according to the internet "The Quaife maintains scoring of the inner bore of where the halfshaft seats in the differential. This is to keep it lubricated and in turn prevent seizure. The Wavetrac does not have that and the stock open diff does."
