2004-2021 Subaru STI ACT XACT Prolite Flywheel

600240 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.

Features

  • Dramatically improved engine response and acceleration, mild to moderate gear rattle
  • Heat-treated forging for strength and toughness, induction-hardened ring gears for maximum life
  • 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
  • Recommended for race use
  • Forged, CNC machined and dynamically computer balanced for smooth high RPM reliability

Benefits

  • Designed for best throttle response and acceleration
  • Materials are properly distributed for maximum strength
  • Good heat tolerance and rigidity

Applications

  • 2004-2021 Subaru WRX STI
  • 2007 Subaru Legacy GT spec.B (6-Speed)

Run this flywheel in all my subaru’s

I run this flywheel in both my WRXs and for good reason. As soon as I hit boost the revs are amazing and it climbs fast. 5/5 for ACT as usual.

ACT Prolite Subaru STI

By far my favorite upgrade yet! If I had known how much a lightweight flywheel improves engine response I would have done it sooner. Doing some math on the effects of driveline inertia, taking 10lbs off the flywheel is equivalent to taking 220lbs out of the chassis (in 1st gear). Top notch OEM quality from ACT too, with no noticable negative effect on daily drivability or comfort.
