Fidanza 88-92 Audi 80 / 88-92 Audi 90 / 89-91 Audi 100 Aluminum Flywheel

If you're working on your 1988-1992 Audi 80, 1988-1992 Audi 90, or 1989-1991 Audi 100 and looking to improve performance, this aluminum flywheel from Fidanza is a solid option. It's designed to be significantly lighter than the stock unit, which helps free up some horsepower and makes a noticeable difference in how quickly the engine can rev. This lower rotational mass means you'll feel a quicker throttle response, especially when you're accelerating from a stop or coming out of a corner.

Fidanza builds these flywheels with a billet 6061 T6 or 2024 T4 aluminum body, which is a strong yet lightweight material. The friction surface is heat-treated for better grip and longer life, and it's a replaceable part, so you don't have to replace the whole flywheel when the friction surface wears down. They also use military-spec fasteners to ensure everything stays securely in place, which is important for reliability. The ring gear is made of hardened 1050 steel and is also replaceable, making this a well-built component designed for longevity.
