Product Description

The ACT 600145 XACT Streetlite Flywheel is a premium lightweight performance flywheel engineered to improve engine responsiveness and acceleration on select Mazda rotary-engine vehicles from 1986-2011. Precision-forged from chromoly steel with induction-hardened ring gears and CNC machining, this flywheel offers enhanced strength and heat tolerance compared to stock components. The one-piece design provides uniform, efficient heat transfer and reduces the risk of warping or failure under spirited driving conditions.

Dynamically computer-balanced for smooth operation at high RPM and recommended for both street and race use, the ACT 600145 significantly reduces rotational inertia to deliver quicker rev response and better throttle feel. This direct-fit performance flywheel suits Mazda RX-7 (Turbo and naturally aspirated) and RX-8 models equipped with 1.3 L rotary engines, making it an excellent upgrade for enthusiasts seeking improved drivability, responsiveness, and reliability on both street and track. Flywheel requires counterweight for installation (not included).
