The ACT XACT Prolite flywheel for the 1987 Mazda RX‑7 is a lightweight, low-inertia option designed to sharpen throttle response and improve acceleration. Prolite flywheels distribute material for maximum strength, heat tolerance and rigidity; they are serviceable and can be resurfaced without extra parts, and are commonly chosen for road or rally driving where reduced rotating mass enhances responsiveness.
