EBC GD1663 Front Performance Rotors for BMW with ATE Front Calipers

Transform your stopping power with EBC GD1663 front grooved and dimpled rotors. Built for fast-road use and confident daily driving, these heat-managed discs pull cooling air across the face to help control temperatures, curb fade and keep pedal feel consistent. The dimple pattern vents gases without full cross-drilling, reducing the risk of stress cracking. Finished in a smart black anti-corrosion coating for an OE-plus look that lasts.

We have installed GD Series rotors on customer cars and our own builds at MJ Modifications and the feedback has been superb. Sharper initial bite, steady braking under repeated stops and a more reassuring pedal. If you want a proven upgrade for ATE-equipped BMW models, GD1663 is a standout choice.

Why enthusiasts choose GD1663

• Grooved face sweeps the pad to help maintain a clean contact surface and even pad wear
• Dimpled design releases friction gases while avoiding the cracking risk linked to fully drilled patterns
• Directional slots aid airflow to manage heat and reduce fade during spirited road use
• Thermic Black coating helps resist rust for long-lasting good looks behind your wheels
• Stable, confidence-inspiring pedal feel and strong bite with quality road pads
• Engineered specifically for ATE front caliper applications
