Some people say the shorter ratio might slow the car down... to be honest, I don't know.. considering that our DCT shifts soo fast. Then again, I use launch control for my best run.. from what I'm hearing, you have your traction control off and you just throttle in; is that correct? I might try to get a set of radials for spring time then.
Awesome job man - really nice stuff. I still remember last spring, everyone doubted that our M3s will break 11s. Your run clearly shows that a well tuned M3 will shatter the 12 second mark! Keep pushing it!
