nearly everything was discussed in terms of tuning the 1M (except RB's i guess
) however I couldn't find anyone interested in a short ratio diff.
Dinan offers 3.45/3.62 diff options which give 9.5% and 14.9% torque increase respectively, which seems nice for a diff upgrade only. these are listed under the M3 DCT which is identical to our diffs.
anyone have experience in this? after some
i found that biglare had this mod on his previous E90 M3.
It would be nice to know everyones feedback!
