The Clutch Masters “Big Boy” is a package from Clutch Masters designed to squeeze optimal performance and engagement out of your 2002-2005 WRX without overstraining the fragile OEM transmission, all while offering smooth engagement and only slightly stiffer pedal feel. What’s the secret? a 242mm (9.5in) clutch housing coupled with a specially designed 9.5LB aluminum flywheel, as well as a 2600lb capacity pressure plate (for basis of comparison, the stock pressure is around 1500 lbs, and most traditional aftermarket clutch kits are about 2000 lbs.). The increased surface area (9.5in as opposed to the stock 9in) improves the clutch disc’s performance while still offering a great street and daily drivability, and in many cases, increased disc life.
Kit includes a heavy duty pressure plate (2600lb of clamp) and steel-backed organic lined disc, featuring smooth engagement. This assembly is designed to provide extended life and superior holding power for cars with moderate power upgrades and/or more enthusiastic driving in extreme conditions. Most organic discs provided in Clutch Masters’ assemblies include steel-backed lining to enhance the structural integrity of the material which is complemented by the highest quality hub assemblies available to ensure durability and drivability.
Torque Capacity: 375-400 ft/lbs.
Kits Include: 9.5LB aluminum flywheel, 2600lb high-clamp pressure plate, performance clutch disc, alignment tool and all necessary hardware and bearings.
