Clutch Masters 04-11 WRX STi 2.5L 6 spd T FX850 Twin Disc Street Clutch Kit w/ Steel FW Pull-Type - cm15017-TD8S-SW

Clutch Masters is proud to introduce the finest and most economical multi-plate clutch systems available for today’s high performance vehicles, the 725 and 850 Series. Clutch Masters Twin Disc systems are pure racing technology that also works well in high performance street applications. They are designed to hold tremendous horsepower and torque ratings, while retaining a very smooth operation. By slightly increasing the clamping force of the pressure plate and adding to the square inches of usable disc area, CM Twin Discs significantly increase clamping values with only a 25-50% increase in pedal pressure depending on the application. The cover assembly is machined from billet aluminum with 25% more tensile strength than the competition’s cast unit. The flywheel is machined from billet 6061-T6 aluminum to meet SFI spec 1.2 for competition in NHRA, NDRA, IDRC, IHRA, SCCA and NASA. Each aluminum flywheel includes a replaceable heat shield. Steel flywheels are also available on select applications. *725 SERIES* – (7.25” Twin Disc) The 725 series is a smaller diameter assembly, which creates less rotating mass and offering quicker, and smoother shifting with much better throttle response. *850 SERIES* – (8.50” Twin Disc) The 850 series is a larger diameter assembly, which is designed for high horsepower applications that require smooth engagement, quiet operation and high clamp load. *All systems include:* * Cover Assembly with attached Diaphragm * Pressure Plate Ring * Two Discs * One Mid Plate * Billet Aluminum Flywheel * Release Bearing * Pilot Bearing (when applicable) * Pressure Plate Bolts PartNumber : cm15017-TD8S-SW Description : 850 Series Twin Disc; 8.50in Disc (Race/Street); Steel Flywheel Included; Pull Type 2004-2014 Subaru Impreza WRX STI H4.2458cc Drivetrain::Clutch Kits - Multi 2007 Subaru Impreza WRX STI Limited H4.2458cc Drivetrain::Clutch Kits - Multi 2011-2014 Subaru Impreza WRX STI Limited H4.2458cc Drivetrain::Clutch Kits - Multi 2010 Subaru Impreza WRX STI Special Edition H4.2458cc Drivetrain::Clutch Kits - Multi 2007-2009 Subaru Legacy GT spec.B H4.2458cc Drivetrain::Clutch Kits - Multi 2015-2017 Subaru WRX STI Base H4.2458cc Drivetrain::Clutch Kits - Multi 2015 Subaru WRX STI Launch Edition H4.2458cc Drivetrain::Clutch Kits - Multi 2015-2017 Subaru WRX STI Limited H4.2458cc Drivetrain::Clutch Kits - Multi 2016 Subaru WRX STI Series.HyperBlue H4.2458cc Drivetrain::Clutch Kits - Multi
