Though clutches rank below power-adders on the desirability scale, they are every bit as important. In fact, you’d be better off not spending the time and money on a trick blower or turbo kit if you do not plan on upgrading the stock clutch assembly. Sure, it is possible on some applications to improve the performance of your motor without a clutch and pressure plate upgrade, but you can only take things so far. Eventually, the engine will let you know by racing to the moon when you least expect it. Your clutch will likely slip under full throttle, and most probably at the highest load. Better hope you have a rev limiter or things can really get ugly. But have no fear … Advanced Clutch Technology (ACT) has come up with a variety of effective combinations to cater to the needs of performance enthusiasts and racers.
