My Backdraft RT4 was new a year ago, Coyote & Tremek TKO 500. The clutch pedal came with an adjustable long bolt ( with a front & back locknut on each side of the tab ) and after a few adjustments, I was able to get the clutch releasing better than when the car was delivered. Having said all that, the Tremec TKO 500 is a terrible shifting transmission. The Ultra Shift
Synthetic trans fluid made a big difference, and the transmission is now marginally acceptable. Next on the list is the Liberty Gears upgrade to the trans to shift like it should. Hope that helps. Mark
