E36 diffential ratios
Posted: Tue Nov 13, 2007 12:08 pm
I have heard that the housing for an M3 evo diff is unique, for the prop from the 6 spd box. The stock gear ratio is 3.23:1, how easy is it to up the ratio to 3.43:1 or 3.64:1 say, and is there any other bmws that contain such gearset ratios that would be compatible?
