If you have a T-5 on the other side of the engine I don't suggest any hard hitting clutch. My stock T-5 went through hell and came back begging for more for about three years of powershfiting. I wasn't making your power though. A month after the Spec III install, (two weeks of break in) the input to countershaft teeth sheered each other off. However, the Spec III is a badass clutch, and works great with the TKO500.
