The ACT Prolite flywheel kit with counterweight for 2004 Mazda RX-8 supports rotary RX-7 and RX-8 applications, offering ACT's lightest XACT flywheel with reduced inertia for sharper throttle response and quicker acceleration. Materials are distributed for strength, heat tolerance and rigidity. Preferred for road and rally use, the serviceable flywheel can be resurfaced rather than replaced.
