EBC S9KR1558 S9 Rear Brake Kit - Yellowstuff High Friction Pads and USR Slotted Rotors

The EBC S9 brake pad and rotor kit, part number S9KR1558, is a matched rear-axle upgrade that pairs EBC Yellowstuff high friction brake pads with EBC USR fine slotted sport rotors. EBC's part-number convention marks KR kits as rear-axle kits, so this set replaces the rear pads and rotors together rather than mixing new friction with worn discs.

Yellowstuff is EBC's flagship GG rated compound for maximum brake effect, fully shimmed, chamfered and slotted, and finished with the patented EBC Brake-In coating for fast pad seating. Compared with the GD-based S5 kit, the fine slotted USR rotors in this kit cut wind noise under braking.
