EBC Brakes USR1670 Ultimax Slotted Rear Brake Discs/Rotors (Pair) for BMW 1 Series 123i E82/E88 ATE Calipers – Thermic Black Coated Grooved Rear Axle OE Replacement Performance Set

USR1670 Rear Grooved Rotors for BMW 1 Series 123i ATE Fitment

Give your back brakes the upgrade they deserve with this set of EBC USR rear grooved discs for the BMW 1 Series 123i. Engineered for cars running ATE rear callipers, these precision slotted rotors deliver a confident, progressive pedal with quiet operation for daily driving and spirited road use. The slim, swept grooves evacuate gases and help manage heat while keeping wind noise low, so you enjoy clean, consistent bite mile after mile.

Finished in a durable Thermic black anti-corrosion coating applied in the UK, they look smart behind the wheels and stay that way. The slot layout encourages uniform pad contact to help reduce judder and maintain smooth braking throughout the life of the disc and pad set. Unlike cross-drilled alternatives, the solid slotted design is engineered to resist cracking.

We run these on customer cars and our own builds, and the feedback is exactly what enthusiasts want to hear: quiet in use, strong and predictable stopping power, and a reassuringly smooth pedal feel. Pair them with Redstuff, Greenstuff or Yellowstuff pads for a balanced fast-road setup.
