Product Description

The EBC S9KR1277 Stage 9 Rear Brake Kit is engineered for Lexus performance sedans and coupes requiring stronger stopping power and improved braking consistency. Combining EBC's high-friction Yellowstuff brake pads with USR fine-slotted sport rotors, this package delivers enhanced pedal feel, superior fade resistance, and increased braking confidence during spirited driving.

Yellowstuff pads utilize an advanced aramid fiber friction compound designed to provide strong cold bite while maintaining excellent performance under elevated temperatures. The included USR rotors feature precision-machined narrow slots that help evacuate dust and gases while continually refreshing the pad surface. This design promotes consistent braking performance without the excessive noise often associated with aggressive rotor slot patterns.

Finished with EBC's Geomet anti-corrosion coating, the rotors offer long-lasting protection against rust and environmental exposure. As a direct-fit rear axle upgrade for compatible Lexus GS, IS, and RC models equipped with the factory 309mm rear brake package, the S9KR1277 provides an ideal balance of daily drivability, performance, and durability.
