General Description:
For years lightweight flywheels have been used to distribute the horsepower that an engine creates more efficiently. Aluminum flywheels will add much more performance to your engine. Because the factory built flywheel is so heavy and so large in diameter it takes an immense amount of power just to get it rotating.To rotate the factory flywheel from 1000 rpm to 6000 rpm can take as much as 40 horsepower. That same application with an aluminum flywheel, because of its? lighter weight, takes less than 15 horsepower.

This means that the horsepower the engine is saving is actually sent to the wheels and not spent rotating the heavy steel flywheel.To establish this as fact and not theory, we have tested time and time again. Both the dynamometer and track results have shown conclusive evidence that a light weight aluminum flywheel is a must. With all the benefits of the lightweight flywheel, driveability is virtually unchanged and in most cases improved. Whether the car is your daily driver or a pure race machine, Fidanza has the flywheel to suit your needs. Our 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 1050 steel.The plates are milled to meet our high specifications. A Fidanza flywheel can mate with any type of clutch material, including organic, kevlar, ceramic, metallic and sintered iron. We attach the friction surface with military grade aerospace fasteners. 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.We were the first to utilize a stepped dowel system in most of our flywheel applications. This doweling method ensures that once the pressure plate is installed the dowels cannot be removed because they become locked into place.

Fidanza designs and builds flywheels with extreme precision.We give tuners, racers and builders the high performance and unmatched power they're seeking.​

This may be an EXTREMELY stupid question. But I'll ask it anyways. Flywheels, Slip Differentials, (and possibly clutches? though I'm pretty sure not)... are any of these made or necessary on Autos?
