@GeorgeSmooth
i read you have a 335i with Automatik Transmission. Did you change the axle ratio too?My 335ia has i think 3,46 and the m3 diff from DCT dubble clutch has 3,15. that was longer then mine. i dont want to lose acceleration
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
