Let's examine what changing the ratios does: SPEED IN GEARS '96+ E36 M3 final drive gearing remains the same in the 5-speed or 6-speed, same ratios in both gearboxes 1st-5th. 3.23 is the standard ratio in '96+ M3 whether fitted with 5-speed or 6-speed. That is why for instance an MGB with 14″ wheels was fitted with a 3.90 gear ratio and the earlier MGA with 15″ wheels had a lower gear ratio. Here are some typical ratio numbers with the gear teeth counts (Pinnion/Crown Gear): Big Healey: 4.10 10/41 3.90 11/43 3.545 11/39 MGT: 5.125 8/41 4.875 8/39 A graphical text difference analyzer.

That means that in general, you can swap most non-engine parts between any two E30 models (considering model year changes across the board, and 2-door vs. 4-door differences). A great resource for comparing part numbers across models is RealOEM.com. This site is helpful for E30 ... You have a 325 so I'm not too sure about your tranny ratio's but as long as you're raising the redline it will compensate for the diff, but some people might not feel 3rd gear is too tall on many (most?) tracks, while 2nd is too short. Changing the rear end ratio lets the 330 come out of turns a lot better, at, say, Summit Point.
