Typical benefits of a lightweight flywheel for various engine types:
• Reduced mass equals increased acceleration.
• A lightweight flywheel works particularly well with turbo-charged engines because it reduces typical turbo lag.
• Increased supercharger efficiency due to less parasitic drag on the crank.
• Improved mid-range torque in a normally aspirated engine due to not having to overcome the heavy weight of a stock flywheel.
• CM uses only 6061-T6 aircraft grade or better billet aluminum in the manufacturer of its flywheels.
• CM uses A36 steel for the friction surface.
• CM uses an OEM steel ring gear secured by bolts.
• CM offers a limited lifetime warranty.

An excellent performance upgrade. Because aluminum is lighter than steel, Clutch Masters aluminum flywheels are able to be produced in stock dimensions. Aluminum flywheels are perfect for road racers looking for quicker revs. It is also a nice complement for turbocharged cars experiencing lag.
