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 a SMF and here is why:

• DMF’s tend to be more expensive than a 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 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 are able to be resurfaced and can be reused.
