With a few more simple mods (FMIC, DP's, aggressive map and meth), they can go mid 12's with little trouble.
All said I really didn't want to go this route with my 135i so I switched back to the SS. My SS goes pretty good now as well (see mods in sig)...

I'm doing all I can to talk my daughter into the 135i when the used market is plentiful and i can steal a nice babied car. Then turn up the juice as she shows discipline and the ability to handle the car at the track.
Killer car and I WANNA DRIVE IT TOO!
It's that or a Sky Redline and the 2 seater is just no good when you wanna have friends ride along.
