Product Description

The EBC S4KR1358 Stage 4 Redstuff Rear Brake Kit delivers upgraded stopping power and cleaner performance for Audi Q5, SQ5, S4, and S5 models equipped with 330 mm rear rotors. This kit pairs Redstuff low-dust ceramic pads with precision-engineered USR slotted rotors, offering shorter braking distances, improved heat management, and quieter operation than OEM components.

Designed as a direct bolt-on replacement for factory rear brakes, it requires no modifications and retains full compatibility with the stock calipers and parking-brake system. The Geomet-coated rotors resist corrosion and maintain balanced braking performance for everyday driving, spirited use, or light track conditions. For optimal braking balance, pair with the corresponding EBC Stage 4 front kit.
