E36 M3 Alignment Guide
I – Introduction:
This FAQ was designed for anybody interested in E36 suspension.
Organization is by axle. Each specific item contains a description, and BMW OE part numbers. Some components also include a failure mode description. Note that only major components are covered. Small bolts, nuts, and interconnecting pieces are not referenced. I suggest www.realoem.com for locating specific things.
I use the word OBD1 M3 to describe the 1995 US model year M3 with the S50B30 engine. OBD2 M3 to describe 1996-1999 US model year M3s with the S52B32 engine. 3-Series to describe 328, 325, 323, 318 i, si, ic, and ti cars with M50, M52, and M4x series engines. This guide is focused on US spec cars, although much of this information no doubt applies to the world market as well. Also perhaps, but not necessarily, applicable to the E36-based Z3 Roadster and Coupe
