Ok, so after a year and a half of ownership and some good time at the track, it's time for me to replace the clutch. Anyway, I've done some research and talked to a couple of friends, and they all recommended the Sachs clutch kit. So what is your opinion on this? Any other possibilities? Specific things that I should know/expect from this model? BTW, the car is currently rated at ~452hp/410lb-ft.
