If you're serious about performance, the Advanced Clutch XT/Race Rigid 4 Pad SB11-XTR4 kit is where it's at. This setup is built for those who really push their machines to the limit. The Xtreme pressure plate is not just a flashy name—it's designed with an exclusive diaphragm that cranks up the clamp load while minimizing deflection. What does that mean for you? Longer clutch life and better performance, plain and simple. Plus, every diaphragm goes through a four-stage heat treatment process, so you know it's tough enough to handle the heat when you're out there on the track or tearing up the trails.
The pressure plates are precision-stamped for added rigidity and consistency, which is crucial when you're shifting gears at high RPMs. Speaking of shifting, this kit features 4-pad rigid race discs made from high-quality ceramic friction materials. The chrome-moly hub is heat-treated too, giving you the strength and durability you need for aggressive driving. The lightweight and rigid design makes for quicker shifts and smoother operation, though I’ll be honest—the engagement is a bit harsher. But hey, that just means you’re getting faster shifts, and if you’re in a smaller engine, this setup is perfect for those compact disc sizes.
