I apologize if this is a duplicate post. TC Kline is at it again with the F80, dominating Mid Ohio.
For those who aren't familiar with TCKR, they make excellent suspensions for BMWs. The owner (TC) is involved and oversees the design, manufacturing, and testing of TCKR suspensions. If I still had an F80, this would be my go to setup for track and street.
Enjoy.
