• Light-weight for improved performance and Quicker Rev's
• (Aluminum Flywheels) Consist of a replaceable heat shield (friction surface), eliminating need to resurface flywheel
• Reduces turbo lag in turbo-charged engines
• Increased supercharger efficiency due to less drag on the crank

• Replacing your OEM flywheel with a light weight flywheel may cause gear noise or a vibration that may not be suitable for everyone. The lighter the flywheel the more gear noise will be produced. Depending on the application, Clutch Masters usually recommends Steel flywheels rather than Aluminum flywheels since Aluminum flywheels will cause more gear noise. Aluminum flywheels are usually only recommended for race applications looking to have the least amount of weight as possible. A light weight flywheel may affect the life expectancy of a clutch kit depending on the application.
