The FX300 System uses the Power Plus I Pressure Plate with the Steel Back Segmented Kevlar disc. This clutch is disigned for the ultimate street enthusiast or weekend racer running a normally aspirated car equipped with cylinder head work and/or hotter cam(s), or with medium-boost turbo or super-charger, or up to 100hp Nitrous. The FX300 features only slightly increased pedal pressure (overstock components), long life disc and smooth engagement.
