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 Kevlar material on the pressure plate side. This provides a smooth but positive engagement. The lightweight, un-sprung 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 significantly quieter 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. Customers all over the world use this clutch at elevated power levels and are extremely happy with the drive-ability. We recommend this clutch for all high output MQB/ MQB EVO cars, as well as FSI / TSI cars that have turbo upgrades. The RSR Hybrid is also commonly paired with performance ecu software from companies that offer drive train warranties with their software programs.
