This is epic ! Thanks OP ! I knew BMW would not modify the e90 body THAT much for the M3. They had to stop somewhere...
I would like this diff along with a final drive such that it would not modify the stock drive ratios. Anybody knows if this would be possible ?
EDIT: Wow, checked out and the gearbox ratios for the M3 manual and 335i manual are the same ! So I think that fitting a 3.08 final drive on the M3 LSD keeps the stock 335i 6MT drive ratios...nice
EDIT 2: The DCT M3 differential has 3.15 final drive ratio, pretty close to the 3.08 of the stock 335i 6MT...
