Fidanza 07-09 Pontiac Solstice /Saturn Sky Redline Aluminum Flywheel (12.5 lbs)

The billet 6061 T6 aluminum body of this Fidanza flywheel is a key detail, making it significantly lighter than the stock unit. This lower MOI (moment of inertia) means the engine can rev up and down more quickly, translating to faster throttle response and improved acceleration, especially noticeable when you're pushing your Redline model hard. It weighs in at a mere 12.5 lbs, which is about 40-60 percent lighter than what came from the factory.

Fidanza builds these with a heat-treated friction plate designed for solid grip and long life, and importantly, this plate is replaceable. If it ever wears out, you don't need a whole new flywheel. The ring gear is also hardened 1050 steel and is bolted on, so it too can be replaced if necessary. They even use military-spec fasteners to ensure everything stays put reliably. This flywheel is a direct bolt-on replacement for your specific application.
