Fidanza 08 Evo 10 4B11T 9.0lb Aluminum Flywheel (13.4lb OEM)

Fidanza is known for making well-built aluminum flywheels that help engines rev faster. This particular flywheel is designed for the 2008, 2010-2015 Mitsubishi Lancer with the 4B11T engine. It weighs in at a mere 9.0 pounds, which is significantly lighter than the stock 13.4-pound unit. This reduction in weight means less rotational mass for the engine to overcome, leading to quicker acceleration and a more responsive feel when you blip the throttle.

The body of this flywheel is made from billet 6061 T6 or 2024 T4 aluminum, chosen for its strength and light weight. It features a heat-treated friction plate that's designed for good grip and a long service life, and this plate is also replaceable if it ever wears out. Fidanza also uses military-spec fasteners to ensure reliability, and the ring gear is made of hardened 1050 steel, which is a strong material for this application. The lower MOI (moment of inertia) is what directly contributes to that faster throttle response you'll notice.

This flywheel is a bolt-on replacement for your factory unit. The stepped dowels help ensure proper alignment during installation, and the replaceable friction plate means you can service it down the road without needing a whole new flywheel.
