ay? you talking about the M3 spec eccentic CAB? if so Im pretty sure camber deson't change. The caster, however does change, increasing high speed stability.

Haven't read all of the posts but why cant you just measure how far down the pistons travel in the block? 'e' crank will be 81mm and i crank will only be 75mm. As for lack of power if 2.7i conversion has been done poorly it is possible the c/r will be low, or its just a stock e motor which are slow ...

I don't get you lot as number 1.
Guess its a different list depending on where you are.

I also thought the 325i rear end has bigger/stronger CV's. 325 come with med. case diff, most 320 I've seen have small case.
