This clutch disc was developed to increase the torque capacity over the original RSR clutch disc without having a significant increase in clutch pedal effort. The Hybrid disk is a complete redesign from the original RSR disc, utilizing an HD organic friction material on the flywheel side, and a segmented, sintered kevlar material on the pressure plate side. This provides a smooth but positive engagement. The lightweight, unsprung hub keeps the mass of the disc as low as possible. We also made a change that puts the engagement point slightly further up the pedal travel than the original RSR, or roughly in the stock engagement point area. Although the RSR hybrid isn’t silent at idle without the clutch pedal depressed it’s notably more quiet than most single mass clutches, and it does not have any of the noise that single mass kits have during low rpm acceleration or high rpm deceleration. A great deal of time, effort, and testing went into this clutch. The results have been very positive! We recommend this clutch for all high output MQB cars, and FSI / TSI cars that have turbo upgrades.
