Clutch Masters Lightweight Steel Flywheel - VW / Mk7 / Golf / R | FW-450-SF

Clutch Masters Flywheels are designed and tested to ensure the safety and quality of every flywheel. Years of R&D have given us the knowledge and firsthand experience to choose wisely the best material to manufacture flywheels that will surpass your expectations. Depending on the application, most Clutch Masters flywheels are made from 1045 or 4140 Billet Steel. Clutch Masters Flywheels are SFI Certified, meeting automotive and motorsport industry performance standards.

Going from a Dual-Mass Flywheel (DMF) to a Single-Mass Flywheel (SMF):

A Dual Mass Flywheel (DMF) is a flywheel in two concentric parts or two facing flywheels stuck together with a flexible compound to damp down transmitted vibration and gear rattle for the gearbox. Many newer model vehicles now come standard with a factory DMF. Many times enthusiasts choose to replace a DMF with an SMF, and here is why:

• DMF’s tend to be more expensive than SMF.
• DMF’s are not designed to be resurfaced like conventional SMF.
• DMF’s usually weigh 30+ lbs depending on the application, which will cause unwanted turbo lag.
• DMF’s cannot withstand a high abuse rate and may fail under spirited driving.

Note:

Replacing your OEM flywheel with a lightweight 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 with the least weight possible. A lightweight flywheel may affect the life expectancy of a clutch kit depending on the application.
