Product Details
Improved low end throttle response. Smooth operation. Less lost power off the line. Give your B5 1.8T the clutch it deserves. Combine the new ECS Tuning lightweight flywheel with an S4 clutch kit, capable of handling 295ft-lbs of torque, for increased power transfer and faster revs 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.
Stronger and tougher than the original. If performance is job one on your to-do list, ECS Tuning flywheel kits deliver.
