Having a few 'issues' with our 325 at the moment, and need some clarification if possible.
Just to explain what the confusion is, we're rebuilding a 325 racer, which has Porsche calipers on the back (new brackets welded to hub). Dan wanted to 'off' the handbrake mechanism, which we dont need, so we stripped the hubs down, which is when we noticed that each side had a different bearing, the right hand one being 'correct' for anything from a 318 to a 325 (according to euro car parts website, anyway) and the left hand one having the smaller bearing as fitted to 316 and, it seems, the later 3 series compact. The drive flange on this side is also thinner, but still has the same 4 stud spacing as the thicker one on the right hand side. Obviously we want to make the left hand one the same as the right hand one!! simples.
So the question is - will any disc brake hub be 'right', or are there a gazillion different combinations?
Thanks for looking
Kim
p.s. Just to clarify, the above 'mods' were carried out before we owned the car, and are just the latest in a very long list of bodges which we are having to undo before the thing is fit to race.
