Great build. Alum block M52 is what I have been wanting to do too. Interesting to see how much farther the Z3 hubs push the wheels out. Do you know if it is just the hubs doing that or maybe the trailing arms as well? I've read different things about the various trailing arms. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
