ACT
ACT, short for Advanced Clutch Technology, is an American clutch maker. Its range here covers the whole clutch assembly: complete kits, clutch discs, pressure plates, flywheels, release bearings and the small parts in between.
The discs show how the range is organised. Street discs come sprung or rigid, and race discs use four-pad or six-pad designs, again sprung or rigid. Pressure plates are listed as Heavy Duty or Xtreme and the XACT flywheels as Streetlite or Prolite, and twin-disc and Mod-Twin kits are listed as well.
The listings favour Japanese cars. Honda leads, followed by Mazda, Ford, Toyota, Nissan, Mitsubishi and Subaru. The Honda Civic and CRX, Mazda RX-7 and Toyota Supra (A80) have especially wide coverage.
Elsewhere in the Transmission & Clutch section, other brands supply shifters and linkages. ACT is the brand for the clutch itself. Discs, pressure plates and flywheels are also sold on their own, so you can replace a single worn part without buying a full kit.

Description
600521 is a Prolite flywheel, which is ACT’s lighter flywheel offering with lowest inertia. Prolite flywheels are designed for best throttle response and acceleration. Prolite flywheels are preferred for road racing or rally racing, and have reduced drivability. Materials are properly distributed for maximum strength, good heat tolerance and rigidity. ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.
Feel:
Dramatically improved engine response and acceleration, mild to moderate gear rattle
Life:
Heat-treated forging for strength and toughness, induction-hardened ring gears for maximum life
Quality:
One piece construction allows less opportunity for failure and provides uniform efficient heat transfer from the clutch disc. No more warped inserts or loose ring gears
Recommendation:
Recommended for race use
Difference:
Forged, CNC machined and dynamically computer balanced for smooth high RPM reliability
