What good is more horsepower if it isn't transferred to the ground? The clutch is the main link between the power your engine produces and the transmission, but all too often it is also the weak link. Many stock clutches simply will not last under harsh driving conditions or continual hard launches. When a car is making more horsepower than stock the factory clutch is under even more strain. This can cause premature clutch wear and costly repair bills. Spec Clutch solves this problem with their line of performance clutches. With increased surface area Spec clutches give your transmission more 'bite' while increasing reliability and performance.
