Hi im looking to buy a gear set for my m3 differential, my m3 differential is installed in an 335i, i am currently with the 3:85 gear ratio from a manual m3 but its just a bit low for my car, id like to try the 3:15 gear ratio as it would be closer to stock, if anybody out there has idealy a ring and pinion from a dct car or even a whole diff please contact me

Thank you
