Clutch Masters FX300 Clutch Kit for 2004 – 2021 Subaru WRX STI
Even with basic bolt on mods the EJ25 motor in your STI will be getting close to 300HP or even more with some of the newer models of STI’s. At this power level the stock clutch becomes incapable of supporting the upgrades and more aggressive driving from track days. The FX300 clutch kit for the STI offer a 110% increase in holding capacity over factory clutch and is a must have to put the power to the ground for any track ready STI.
The FX300 System uses the Power Plus I Heavy-Duty Pressure Plate and utilizes a sprung steel backed segmented Kevlar disc. This clutch is engineered for street driven vehicles and is specifically designed for extended wear and additional clamping force for the enthusiast who has added minor bolt-ons such as an exhaust and or intake system, up to 50hp NO2, and one of our infamous Brewed tunes. It features only slightly increased pedal pressure over factory, longer life than stock, and normal clutch feel during engagement and disengagement for a very smooth operation.
FX300 clutch kit includes:
- Steel Backed Segmented Kevlar Friction Material
- Heavy-Duty Sprung Hub
- OEM or better Release Bearing
- Pilot Bearing
- Alignment Tool
- Instruction Card
