ACT XACT Streetlite Flywheel for Select Mazda RX-7 and RX-8 1986-2011 (600145)

Fits select 1986-2011 Mazda RX-7 and RX-8 (Turbo and naturally aspirated rotary engines).

The ACT XACT Streetlite flywheel (600145) is engineered to significantly improve engine response and acceleration by reducing rotational mass. Constructed as a single-piece forging rather than a multi-piece assembly, this flywheel eliminates common failure points like loose ring gears or warped inserts. This design also provides more uniform and efficient heat transfer from the clutch disc, ensuring consistent performance during spirited driving or track use.

Every Streetlite flywheel is CNC machined from heat-treated chromoly steel and induction-hardened for maximum durability. To ensure smooth operation at high RPMs, each unit is dynamically computer balanced before leaving the factory.

• One-piece forged construction for superior strength and toughness
• Induction-hardened ring gears for extended service life
• Forged and CNC machined for precise tolerances and high-RPM reliability
• Dynamically balanced to eliminate vibration
• Noticeably improved throttle response and acceleration with OE to mild gear rattle
• Recommended for both street and race applications
