The ACT Prolite Flywheel for the Mazda RX-8 is made from premium quality forged Chrome-Moly steel, CNC machined, and balanced. It also features an induction-hardened integral ring gear, and is durable and thick enough to be resurfaced. Certified to SFI Specification 1.1. The Streetlite RX8 flywheel is light, but not too light, helping you get up into the powerband faster, without dramatically changing the car’s driving characteristics.
Counterweight required for installation. Not included.
