Clutch Masters FX250 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 FX250 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 FX250 System uses the Power Plus I High Rev Pressure Plate with a steel backed friction material on the flywheel side and a combination of Clutch Masters Fiber Tough friction material for the pressure plate side. This kit is specifically designed for extended wear and additional clamping force for the street enthusiast and weekend racer who has moderate modifications to their STI, and also most importantly one of our infamous Brewed tunes.
FX250 clutch kit includes:
- Heavy-Duty Hybrid Disc
- Heavy-Duty Sprung Hub
- OEM or better Release Bearing
- Pilot Bearing
- Alignment Tool
- Instruction Card
**The difference between the High Rev pressure plate and the Heavy Duty pressure plate of 15017-HD0F is the High Rev kits have an even stronger and reinforced pressure plate to withstand higher RPM’s for your built EJ25’s.**
