Description: The XACT Flywheel Prolite (Product Code: 600521) represents ACT's dedication to high-performance components for racing enthusiasts. Crafted from Chromoly steel, this Prolite flywheel offers the lowest inertia in ACT's lineup, ensuring optimal throttle response and acceleration. Designed primarily for road racing or rally racing applications, the Prolite flywheel boasts a reduced drivability factor, making it ideal for performance-oriented driving scenarios. Engineered with materials strategically distributed for maximum strength, heat tolerance, and rigidity, the Prolite flywheel guarantees exceptional performance under demanding conditions. With ACT's commitment to serviceability, the flywheel can be resurfaced without the need for additional parts, ensuring long-term reliability on the track.

Description:

  • Feel: Experience dramatically improved engine response and acceleration, accompanied by mild to moderate gear rattle.
  • Life: Heat-treated forging enhances strength and toughness, while induction-hardened ring gears ensure maximum durability.
  • Quality: The one-piece construction minimizes the risk of failure and facilitates uniform heat transfer from the clutch disc, eliminating concerns about warped inserts or loose ring gears.
  • Recommended Use: Perfectly suited for race use, providing optimal performance in competitive environments.
  • ACT Difference: Each flywheel is forged, CNC machined, and dynamically computer balanced to deliver smooth operation even at high RPMs.

Vehicle Fitment:

  • 2006-2013 Mazda 3 Mazdaspeed: 2.3 L4 GAS FI 2260cc | Turbocharged

Frequently Asked Questions

Are ACT clutches balanced?

Yes! All ACT clutch assemblies are computer spin balanced to within .25 oz-in to guarantee help smooth operation across the entire RPM range. For comparison, stock production clutches are typically balanced to within .50 oz-in. Lower is definitely better!

Will an ACT clutch increase pedal effort?

ACT pressure plates are specifically designed to handle high torque applications. With ACT's durable design, expect an increase in pedal effort between 15-40% (Heavy Duty) and 50-80% (Xtreme), depending on the application. Clutches developed with less pedal effort often result in a lack of longevity, torque capacity and/or engagement quality.

Do ACT clutches require a break-in period?

For organic street discs, we recommend breaking in the clutch for 300-500 miles with mild engagement, such as stop-and-go city driving prior to racing or spirited driving. ACT race discs usually only require a few hard slips to lap in the surfaces prior to normal driving or racing. Do not overheat the clutch during the break-in period, as this can result in friction surfaces fusing together, hot spots, and friction surface glazing.

Are ACT clutches repairable or rebuildable?

In some situations, rebuilds or repairs may be possible (see warranty), after inspection of the clutch assembly. Please contact our technical department for further information. Because of special modifications, we do not recommend servicing by a general clutch rebuilder.

How much does an ACT clutch weigh?

The weight of the ACT clutch assembly will usually be the same as a stock OEM clutch assembly.
