Clutch Masters Steel Flywheel - Single Mass (MK7 Golf R)

Clutch Masters Flywheels are designed and tested to ensure the safety and quality of every flywheel. Years of R&D has 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, the majority of Clutch Masters flywheels are made from 1045 or 4140 Billet Steel. Clutch Masters Flywheels are SFI Certified meeting performance standards for the automotive and motorsport industry.

Benefits of a Clutch Masters Light Weight Flywheel

• Light-weight for improved performance and Quicker Revs.
• Reduces turbo lag in turbo-charged engines.
• Increased supercharger efficiency due to less drag on the crank.
• Improved mid-range torque in naturally aspirated engines.
• CNC Machined and balanced.
• SFI Certified.

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 flexible compound to damp down transmitted vibration and gear rattle for the gear box. Many newer model vehicles now come standard with a factory DMF. Many times enthusiast choose to replace a DMF with an SMF and here is why:

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

Benefits of switching to a SMF

• Reduced mass equals increased acceleration.
• Reduces turbo lag in turbo-charged engines.
• Increased supercharger efficiency due to less drag on the crank.
• Improved mid-range torque in naturally aspirated engines.
• SMF's are able to be resurfaced and can be reused.
