Clutch Master Aluminum FlyWheel, Lexus SC

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 High Carbon steel for the friction surface. (Replaceable)
CM uses an OEM steel ring gear secured by bolts.
CM offers a limited lifetime warranty.
CM Billet Aluminum Flywheels meet SFI Spec 1.1 or 1.2
