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.
The FX250 System uses the Power Plus I Pressure Plate and a hybrid combination of Clutch Masters New Formula Button on one side and a heavy-duty Steel Back Organic friction lining on the other. This clutch is designed for the street enthusiast or weekend racer who plans to abuse their vehicle on an occasional basis and have a spirited driving style. The FX250 clutch system has a higher holding capacity than a traditional full faced Kevlar without compromising the street friendly characteristics Clutch Masters is known for. *
