Improved low end throttle response. Smooth operation. Less lost power off the line.
The ECS Tuning RA4 lightweight flywheel was engineered to expand the clutch friction disc diameter from 228mm up to 240mm for increased power transfer, while cutting flywheel mass for an improved throttle response. A decreased mass means a lower moment of inertia. Weighing in at only 12 pounds, the ECS single mass flywheel spins up faster and easier than the 26 pound flywheel shipped from the factory. Off the line, that's like pulling 250 fewer pounds of weight.
But light doesn't mean wimpy. Our machined single mass flywheel is amazingly strong and tough enough to handle a performance clutch package, such as our S4,RS4, or Clutch Masters FX300 kit options.
Stronger and tougher than the original. If performance is job one on your to-do list, ECS Tuning flywheel kits deliver.

This kit does not include a clutch kit, allowing you to choose a clutch option that best suits your needs. This flywheel was designed to work with 240mm B5 S4 clutch options only.
**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. Please contact our sales team with any questions.**
