Product Details

Dual mass flywheels allow for fluid-feeling clutch engagements and offer a more luxurious feel than single-mass flywheels. However, with these benefits come significant drawbacks. Why convert from a dual-mass flywheel to a single-mass flywheel?

  • Cost: Dual-mass flywheels are expensive, with the cost of replacement often times is double or triple than that of converting to a single-mass flywheel.
  • Serviceability: Single-mass flywheels can be resurfaced, eliminating the need to replace with the next clutch service. - something that is not recommended with dual-mass flywheels, as they contain a rubber section that is more failure-prone in high mileage application.
  • Simplicity: Single-mass flywheels lack the complexity of dual-mass flywheels, making them inherently more reliable. Dual-mass flywheels contain a rubber damper or hub that will, like all rubber components, wear out with time.
  • Pedal Feel: Many enthusiasts prefer to eliminate BMW's "Self Adjusting Clutch", which has been known to provide an unpredictable, inconsistent engagement point.
  • Driveability: Valeo's conversion kit has been designed to maintain nearly identical clutch and flywheel weight, ideal for keeping the clutch quiet and easy to drive.
