Flywheels do 3 big jobs: they store energy while reducing drivetrain vibration and transferring power. The average daily driver arrives from the factory with a heavy, dual mass flywheel.

ECS's expert engineers have designed & tested a Lightweight Flywheel for the Audi B7 A4 2.0T.

Compared to the stock 24 pound flywheel shipped with your car from the factory, the RA4 flywheel tips the scales at a trim 14 pounds.
For drastically reduced driveline power pulses, RA4 Conversion kits perfectly mate our lightweight flywheel to the RS4 clutch disc.

Having successfully passed SFI certification, this flywheel has an individual SFI serial number found in a laser etching, and on an affixed sticker. This certification means our ECS-engineered flywheel is safe and reliable during the rigors of competitive racing; it's also safe and reliable for years and years of use.
