LSD's?

3.91 Viscous slip differential from a 325iX, but those behave a bit differently over a normal mechanical clutch slip differential

alright, thanks for the info.

if i just get the 3.73 lsd it should give me better acceleration over the open diff right?

cause i do like my 145-150 top speed.

if i go with the 4.10 how drastic is the top speed difference?

well that kind of a dispute, 3.73 LSD doing better in a straight line. Jordan (old member on here) had a print out showing about a 0.1 second gain or smth.

-There's supposed to be an online calculator/equation for you to calculate what a new top speed would be... someone chime in. Remember though that aerodymanics yada yada play a role as well.

what are the gear ratios? i found a top speed calculator.

(s) cars all should have limited slip diffs. There have been a lot of swaps and different ratios installed over the years. Get your ass under your car and look at the tab. I almost bought a 325e a few years back and it had a 3.25 LSD. Proving we know what should be there, but its not always the case.

Easier to control a slide, easier to put the power down exiting a corner, and most of all, easier to control slip-angle. : )
