Performance - Audi RS4 B7 (2004-2008)

Product Details Give your B7 2.0T the flywheel and clutch combination that it deserves. This kit includes the new ECS Tuning Single Mass Lightweight Flywheel with the B7 RS4 clutch kit, capable of handling 314ft/lbs of torque. The ECS Tuning RA4 Lightweight Flywheel, engineered in the U.S. by our leading R&D team for increased power transfer, faster revs, and improved acceleration while providing a smooth and easy clutch engagement. A decreased mass means a lower moment of inertia and, weighing in at only 14 pounds, the ECS single mass flywheel spins up faster and easier than the 23.6 pound flywheel installed from the factory.  But light doesn't mean wimpy. Our precision CNC machined single mass flywheel is amazingly strong and tough enough to handle a performance clutch package and was subjected to long-term performance and durability testing in-house. Designed to accommodate all conditions: from Sunday drives through the country, to the abuse of the track. No matter your driving style or ability, this is the flywheel for you.

(SFI) is a non-profit organization established to issue and administer standards for the quality assurance of specialty performance and racing equipment. SFI certification indicates a flywheel has been certified using industry-standard SFI Spec 1.1 standards by an independent testing body to ensure quality of both design and materials for flywheels utilized in competitive motorsports. This testing requires that the flywheel must hold at 10,200RPM over an extended period of time for validation of durability, design, and construction.  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 street use.    **On our development vehicle equipped with a poly ECS Snub Mount, very slight audible chatter was noticed. Accompanying modifications can also increase or decrease the amount of "NVH" or "chatter" in the drivetrain.
