The EXEDY Racing Clutch 15951HD is a high-performance clutch kit specifically designed for the Subaru Impreza WRX and STI models from 2004 to 2014. This clutch kit is an excellent upgrade for those seeking improved performance, durability, and reliability for their high-horsepower vehicles.
This cerametallic clutch kit features EXEDY's proprietary ceramic disc material, which provides superior heating resistance and longevity over traditional organic and friction materials. The ceramic discs eliminate the need for a heavy flyweight, consequently reducing unsprung weight and allowing for quicker acceleration and better transmission response. The disc also features a smooth surface finish that delivers a progressive engagement feel, ensuring a more controlled lugging and a smoother driving experience.
The clutch kit also includes an aluminum flywheel that weighs approximately 5 pounds less than the stock motor mount adaptor flywheel, reducing the rotational mass and inertia, resulting in more efficient power delivery and quicker engine response. The flywheel is separately engineered and balanced to maintain a perfect balance, reducing vibrations transmitted to the transmission and drivetrain, ensuring smoother power delivery and a comfortable driving experience.
The EXEDY Racing Clutch 15951HD transmission input shaft is engineered with high-strength steel and designed to withstand the increased torque typically found in heavily modified Subaru WRX and STI vehicles. The shaft is also engineered with a hollow design to reduce weight and subsidiary rotational mass.
The kit comes complete with all the required components and hardware, including the pressure plate, clutch disc, flywheel, pilot bearing, slave cylinder, and hydraulic master cylinder, making it a fully functional and complete upgrade solution. The flywheel, pressure plate, and disc are all machined for a perfect fit, ensuring optimal clamping force and longevity.
EXEDY's Racing Clutch 15951HD is the perfect choice for the Subaru Impreza WRX and STI driver who demands superior clutch performance, durability, and reliability, ensuring an enjoyable driving experience on the racetrack or the street.
