jeroen, rear pics come with new set of wheels (hint BBS)...a few more updates and the pics will be here
about the diff, my major thing with this car is driving quite fast on mountain roads (like hill climb), i'll definitely go also to a racetrack, but major thing about my car and what its build for, is having fun on that kind of roads. So 3,4 gear, sometimes second...thats it.
If i switch to the gearbox from the E21 5 spd and 3.64 with 25% lsd, how much difference would it be to the setup I drive now, it's a 4.11 and gearbox from E30 M20B20.
