Bimmerdiffs clutches might be more expensive but they are, supposedly, a more robust clutch material. They should have greater durability under track/autox situations. Now that I think about it, aren't the 168 clutches NLA from BMW? I looked into all this when I was refreshing my diff. Most sites still list parts until someone orders it and they can't get it, just FYI. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
