110% Increase in Holding Capacity - STREET/RACEThe FX350 System uses the Power Plus I, Hi-Levarage, Heavy-Duty Pressure Plate utilizing our Fiber-Tough friction material. This clutch has a slightly increased holding capacity then the FX300 but will have a slightly more aggressive engagement and will produce some chatter. Similar to the FX300 this clutch is designed for the serious street enthusiast who also might spend a weekend and the track and is running a normally aspirated car that has been highly tuned with cylinder head work such as cams, or with a medium-boost turbo or supercharger setup, or up to 100hp NO2. For years enthusiasts have had to compromise durability for longevity for drivability and vice versa, however with our Fiber-Tough material we have closed the gap between these two tradeoffs.
