I would like to know what diff i would be better off with, ive think ive got a 3.91 on my auto touring at the moment, but havent got the supercharger on it at the moment so cant test it.
Also got a 3.25 one off the e30 m3.
If none of these what do you guys recommend i use with my supercharger, oh the cars a 325 also.
Which diff?

3.91 will be very high with a 200 bhp+ engine, making 1st gear useless and the engine screaming (literally) for a 6th gear.
3.25 might be getting on towards being a bit on the low side, but acceptable.

Would a 3.64 work with this? Cos I have one I don't need but wasn't sure if it would be suitable.
