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.
This kit features a heavy duty pressure plate and segmented Kevlar disc for exceptional holding power & long life. Firm, positive pedal feel. The perfect clutch for aggressive drivers that still desire smooth engagement. This clutch will be a little grabbier than the FX100, with increased holding power with improved life due to the segmented Kevlar disc.
Torque Capacity: 450-475 ft/lbs.
Kits Include: 9.5LB aluminum flywheel, 2600lb high-clamp pressure plate, performance clutch disc, alignment tool and all necessary hardware and bearings.
