EBC GD1670 Rear Slotted/Grooved & Dimpled Performance Brake Discs/Rotors for BMW 1 Series 123i E82/E88 (ATE Rear Caliper Only) Thermic Black Coated OE-Size

EBC GD1670 Rear Performance Rotors for BMW 1 Series 123i E82 and E88 - ATE Fitment

Looking for a serious braking upgrade on your BMW 123i without compromising everyday drivability? The EBC GD1670 rear rotors deliver sharper bite, cooler running and consistent stopping power on the road. Purpose-built for BMW 1 Series 123i E82 coupe and E88 convertible models that use the ATE rear caliper, these grooved and dimpled discs feature EBC’s Thermic Black anti-corrosion coating for clean looks and long-lasting protection.

Key advantages

• Spiral grooves sweep away dust and gases for a cleaner pad contact area and more confident braking.
• Shallow dimples aid pad de-gassing without the cracking risk of through-drilled discs.
• Optimised slot pattern helps reduce the whoosh typically associated with aggressive grooves while preserving cooling performance.
• Thermic Black protective coating resists rust on the non-friction surfaces to keep hubs and vents looking fresh behind your wheels.
• Improved pedal feel and fade resistance in fast road use thanks to better heat management and pad refresh.
• Direct replacement sizing for the original rear brake discs on ATE-equipped cars - no modifications required.

Real-world confidence

We have installed and driven on these EBC grooved rear rotors ourselves and customer feedback has been consistently positive. Expect a stronger initial bite, more consistent performance when warm and reassuring stability during repeated stops.

Important notes

• These are rear brake discs.
• Slotted discs can create a light airflow noise under heavy braking. If you prefer a quieter setup, consider EBC USR slotted or plain rotors.
