Can anybody tell me what are the factory standard rear diff ratios (not LSD) on:

325i Saloon (Auto)?
325i Touring (Switchable Auto)?

Are all E30 diffs a straight swap?

Think they were 3.73, auto or manual could be wrong though

I think the early manual sports were 3.64 and the later sports are 3.91
No idea what the ratios are on the auto sports though
Cheers,
Robin

These are the ratios that RealOEM give me when I enter the VINs for the 2 cars, I think I'll have to check myself.

Anybody with Switchable Auto on a 4dr tell me which diff they are fitted with, assuming they haven't put in an LSD?
