someone in germany tell me that its possible to change the ratio. but at first i have to know how it will work with the driveshaft.

if the the connection from the diff is realy beafier than we have to change the driveshaft. hmmmm
I initially used the 3.85 from the manual M3 diff. It was far to short and I was getting wheels spin right through 3rd gear. Then I swopped it out for the 3.15 and I am very happy with it.
