EBC S20K1029 Stage 20 Ultimax2 Brake Pad and RK Rotor Kit Front and Rear

The EBC Stage 20 (S20K1029) is a complete two-axle disc brake kit that pairs EBC's high-efficiency Ultimax2 brake pads with direct-fit RK Series plain rotors for both the front and rear axles. This all-in-one brake pad and rotor kit also includes caliper lube, giving you everything needed for a full brake service in a single purchase.

Optimal stopping performance depends on all four brakes working together — the rear brakes alone account for up to 40% of a vehicle's total stopping power. Replacing the front and rear axles at the same time ensures a balanced, confident brake feel from the moment installation is complete.
