Fidanza 85-91 Porsche 944 Turbo Aluminum Flywheel

This product is a Fidanza aluminum flywheel designed for the 1986-1989 Porsche 944. It includes a heat-treated friction plate, military spec fasteners, a replaceable hardened 1050 steel ring gear, and a billet 6061 T6 or 2024 T4 aluminum body. The flywheel also features stepped dowels on most applications and a bolt-on replaceable friction plate.

This aluminum flywheel is significantly lighter than the stock unit, typically 40-60 percent less weight. This reduction in mass, known as lower MOI (moment of inertia), allows the engine to rev more freely, leading to quicker acceleration and a more responsive throttle. The heat-treated friction plate is built for optimal grip and longevity, ensuring consistent engagement with the clutch. The use of military spec fasteners adds a layer of reliability for critical components.

The ring gear is made of hardened 1050 steel and is designed to be replaceable, extending the life of the flywheel. This part is a direct replacement for your stock flywheel, making installation straightforward as it's designed to bolt on without modification.
