Damn after reading all this I wanna get one. What ratio do you guys recommend for a stock M3?
This seems like a no brainer. 15% more torque and the only downside is lower topspeed...id take that any day. I still have my limiter on so i doubt id have any complaint of capping off at 185mph.
How much is installation?
