Description:
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.
• Clutch Masters uses only 6061-T6 aircraft grade or better billet aluminum in the manufacturer of its flywheels.
• Clutch Masters uses High Carbon steel for the friction surface. (Replaceable)
• Clutch Masters uses an OEM steel ring gear secured by bolts.
• Clutch Masters Billet Aluminum and Steel Flywheels meet SFI Spec 1.1 or 1.2

Q: How do you install a flywheel?
A: We recommend professional installation since dropping the transmission or whole motor is usually needed. Once the transmission is off of the block, you can go ahead and remove your clutch setup and flywheel. Replace the factory flywheel with your aftermarket one, and re-install the clutch. (Buying a new clutch is a good idea at this point since it needs to be taken off anyway.)
Q: What does a flywheel do? Why buy a flywheel?
A: A flywheel is a component of your clutch assembly, and can make a huge difference in how your car responds when you press the gas pedal. Lightened flywheels are made out of aluminum or chromoly, which reduces the rotating mass by dramatically trimming weight as compared to your heavy factory OEM flywheel. Because the lighter flywheel has less inertia, the engine doesn't need that much torque (power) to spin the flywheel to reach the certain rpm. The result is your car's rpm will increase faster. Additionally, the reduced weight alone will give you a bump in power.
