Hey guys I'm looking for a taller final drive for my 08 6MT. I think stock is 3.85:1 and I"m looking for <3.85:1. I've seen Turner has 2.81, 2.93, 3.15, 3.23 etc. I just picked up this M3 about 5 months ago and I commute long distances everyday so I want to make this thing slightly more economical on the highway at 80mph. Anybody have any used diffs that aren't too beat up?
Thanks!
