Hi. I cant find what diff ratio mine has. It was a 320 auto. The specs pages only seem to have spec for manuals. I think I read somewhere its 4.1 to 1. Anyway, Its now revving too high for comfort ( but it accelerates very nicely )
Is it true that the crownwheel and pinion from 3series up to the E36 will fit ?
Alternatively, anyone fancy a swap ? Im not looking for an LSD, open is fine.
Thanks, Neil

E21's came with the same diff ratio no matter manual or auto.
