The Fidanza flywheel weighs 15.5 pounds and the stock flywheel weights 31 pounds. This is a 50% weight reduction. The reduced mass allows the engine to accelerate and decelerate faster. With less engine power being used to accelerate the flywheel more power is available at the wheels to accelerate the vehicle faster increasing performance.
A light weight flywheel is one of the most cost effective performance modifications you can do.
Fidanza aluminum flywheels are made from the highest quality 6061 T6 aluminum. The material is fantastic for strength, heat dissipation and of course reduction in weight. The friction surface we use is an incredibly strong 1045 steel. The plates are milled to meet high specifications.
Fidanza flywheels can mate with any type of clutch material, including organic, Kevlar, ceramic, metallic and sintered iron.
Fidanza attaches the replaceable friction surface with military grade aerospace fasteners. With these replaceable plates, there is no need to replace the entire flywheel when the clutch or flywheel is at the end of its life, saving time and money.
The ring gears we use are also made from 1050 steel and are heat treated for durability. The gears are heated then pressed on and secured with grade 8 button screws.
Fidanza was the first to utilize a stepped dowel system in most of their flywheel applications. This doweling method ensures that once the pressure plate is installed the dowels cannot be removed because they become locked into place.
