Description
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, a 4-puck ceramic sprung disc for quick engagement and tremendous holding power. Be warned that this kit will yield harsh, aggressive clutch engagement. The FX400 application is meant for heavily modified 02-05 WRXs that only see limited street driving and have upgraded gear sets. This kit is the perfect choice for the road-racing or time attack competition WRX tuners.
Torque Capacity: 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.
