ACT’s lightest flywheel for the Scion FR-S or Subaru BRZ, only 10.5 pounds. Expect improved engine response and acceleration from your FA20 with this light weight design.
Prolite flywheels are preferred for road racing or rally racing, and have reduced drivability. Materials are properly distributed for maximum strength, lower inertia, good heat tolerance and rigidity. XACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts. One piece construction allows less opportunity for failure and provides uniform efficient heat transfer from the clutch disc. No chance of warped inserts or loose ring gears. ACT heat treats the entire forging for strength and toughness, and induction hardens our ring gears for longest gear life.
