Fidanza 87-95 RX7 & 04-07 RX8 Aluminum Flywheel Requires Mazda N351-11-521 (Sold Separately)

If you're working on your 1986-1995 Mazda RX-7 or 2004-2011 RX-8 and looking to improve acceleration and throttle response, this aluminum flywheel from Fidanza is a solid choice. It's designed to be significantly lighter than the stock unit, which means less rotational mass for the engine to spin up. This translates directly into a more responsive engine that can rev faster.

Fidanza builds these flywheels with a billet 6061 T6 or 2024 T4 aluminum body, making them 40-60 percent lighter than stock. This lower moment of inertia (MOI) is key to that quicker throttle response you're after. The friction surface is a heat-treated plate designed for optimal grip and a long service life, and it's even replaceable. For added reliability, they use military-spec fasteners. The ring gear is made of hardened 1050 steel and is also designed to be replaced if needed, ensuring the flywheel can last for many clutch jobs to come.

Keep in mind that this flywheel requires the Mazda N351-11-521 clutch release bearing, which is sold separately. This is a direct-fit component designed to bolt on, but always refer to the manufacturer's installation instructions for specific details and any required tools.
