Fidanza 97-11 Subaru Impreza 2.5L NT (Inc RS) Aluminum Flywheel

Fidanza is known for making well-built performance parts, and this aluminum flywheel is a great example of that. If you're working on your 1993-2011 Subaru Impreza, especially the 2.5L NT models like the RS, this flywheel can really wake up your engine's response. It's designed to be significantly lighter than the stock unit, which means less rotating mass for the engine to fight against. This translates directly into quicker acceleration and a more immediate feel when you hit the gas pedal.

The body of this flywheel is made from Billet 6061 T6 or 2024 T4 aluminum, which keeps the weight down while maintaining solid construction. Fidanza also heat-treats the friction plate for better grip and longer life, and it's designed to be a replaceable part. Plus, the lower MOI (Moment of Inertia) really helps with faster throttle response. They even use military-spec fasteners to ensure everything stays put reliably. The ring gear is made of hardened 1050 steel and can be replaced if needed, and on most applications, you'll find stepped dowels for proper alignment.

This flywheel is about 40-60 percent lighter than stock, which is a notable difference you'll feel. It's a bolt-on part, and the friction plate itself is also a direct replacement, making future servicing easier.
