ACT XACT Prolite Flywheel for Select 1986-2011 Mazda RX-7 and RX-8 (600140)

The ACT XACT Prolite flywheel (600140) is engineered to provide a dramatic improvement in engine response and acceleration for select 1986-2011 Mazda RX-7 and RX-8 models. Designed specifically for the high-revving nature of rotary engines, this ultra-lightweight flywheel reduces rotational mass, allowing for quicker throttle transitions and faster gear changes.

Constructed from a single-piece heat-treated forging, the XACT Prolite eliminates the failure points common in multi-piece designs, such as warped inserts or loose ring gears. Each flywheel is CNC machined for precision and dynamically computer balanced to ensure smooth reliability at high RPM. The one-piece design also facilitates uniform heat transfer from the clutch disc, preventing hot spots and ensuring consistent engagement during demanding race use.
