ok i looked it up some more for you and from the looks of it youll pretty much need to swap out the whole rear subframe of an m3 to make it fit your car, there are a couple of other guys inquiring about it on other forums and thats the response they got...from the looks of it youll need to custom build a unit with lsd for it to fit nicely with your setup.
again if anyone else can chime in on this it would be greatly appreciated. ill keep looking up some info for you in the meantime.
