ACT Clutches and IndigoSpeed Flywheels are all we do...and we do them well!

IndigoSpeed aluminum flywheels are made of the highest quality materials.

They are made of 6061 or 7075 aluminum. They are machine cut on our state-

of-the-art CNC machines. Our Indigo flywheels are anodized with Indigo blue

for a beautiful finish. The friction surface is a heat-treated special alloy steel

that is attached with aircraft quality hardware .The ring gear is heat-shrunk on

and the secured with aircraft quality fasteners.

For your bang-for-the-buck, the IndigoSpeed flywheel is the best performance

increase you can make to your street car or race car. Engine life is also

increased by using a IndigoSpeed flywheel. Since our flywheel is so much

lighter there is much less stress on the engines main bearings. Using our

lightweight, aluminum flywheel is a race proven way to improve the

performance of any street or race car. A lighter flywheel means less rotating

mass. Why is that so important? It means that more horsepower is being

applied to the ground. Horsepower gains can vary widely with lightweight

aluminum flywheels depending on what has been done to the vehicle. Some

gains as high as 10 to 30 horsepower have been seen. IndigoSpeed flywheels

are the perfect choice for road racing ,drag racing and autocross.
