The ACT XACT Prolite flywheel kit with counterweight for select Mazda RX‑7 and RX‑8 applications is ACT's lightest offering, built for lower inertia and quicker throttle response. Intended for road and rally use where acceleration matters, the Prolite balances strength, heat tolerance, and serviceability; counterweight is required for proper rotary installation and the unit can be resurfaced when needed.
