XTM Carbon on Carbon Clutches For high powered road race cars, drifting or drag race vehicles that still use the synchromesh transmission, there is nothing equal to a true carbon on carbon clutch. When designed properly and using the right materials, carbon on carbon clutches offer many unique benefits not achievable with conventional materials. Carbon materials have been used for years in F1 and other top forms of racing as a friction material for both clutches and brakes with outstanding results.
	Pressure Plate When your engine puts out performance, you need a pressure plate that can handle it properly. All ACT pressure plates provide a generous increase in clamp load which directly increases torque capacity. ACT pressure plates are offered in...
			Heavy Duty - HD 20 - 50% clamp load increased Stock to moderate pedal feel Best disc to use: Street or Race disc Most certified to meet SFI Spec 1.1 Xtreme - XT 50 - 120% clamp load increased Moderate to stiff pedal feel Best disc to use: Street or Race disc All certified to meet SFI Spec 1.1 MaXX Xtreme - XX 70 - 150% clamp load increased Stiff to very stiff pedal feel Best disc to use: Race disc All certified to meet SFI Spec 1.1
	ACT heat-treats their diaphragms using an exclusive 3-stage process. ACT also hardens the release bearing contact area to reduce wear. Each pressure plate is designed in the optimum working range for maximum clutch life, clamp load, and release travel. Every pressure plate is tested to insure proper clamp load every time.					This graph shows the ACT pressure plates will provide a higher clamp load for a longer distance than typical pressure plates. This exclusive ACT design translates into longer clutch life, a more positive feel and better shifting. There will be an increase in pedal effort ranging from slight to heavy depending on application.
	Street Discs - SFI Certified to Insure Safety (most discs) ACT Performance Street Discs are designed for smooth engagement, quiet operation and improved durability using only the best organic linings and spring center designs. ACT street discs are available in three designs; stock, modified, and performance.
