EBC USR1663 Front Slotted/Grooved Brake Discs Rotors (Pair) for BMW ATE Front Calipers – Fits 1 Series F20 F21, 2 Series F22 F23, 3 Series E90 E91 E92 E93 F30 F31 F34, 4 Series F32 F33 F36, X1 E84 – 120i 125i 220i 225i 320i 420i – Thermic Black Coated

EBC USR1663 Grooved Front Brake Rotors for BMW with ATE Front Calipers

Give your BMW sharper stopping power and a confident pedal with EBC’s USR1663 grooved front rotors. These performance discs use shallow, sweeping grooves to vent pad gases under load, keep the friction surface clean in the wet, and reduce squeal compared with aggressive patterns. The Thermic Black protective coating is applied in the UK to fight corrosion on non-friction areas so the hubs and edges stay smart long after fitting.

Sold as a matched pair for the front axle. One left and one right disc.

Why this upgrade works

• Narrow grooves help control heat and fade for consistent braking during fast road use.
• Even pad contact promotes a stable pedal feel and tidy, parallel pad wear.
• Grooves clear dust, water and debris for reliable bite in all conditions.
• No through-drilling, which helps reduce the risk of crack propagation.
• Thermic Black finish resists rust and delivers an understated OEM-plus look.
• Direct-fit replacement on the front axle for BMW models with ATE front calipers.

We have installed these many times at MJ Modifications and our customers consistently praise the quiet operation, strong initial bite and long-lasting finish.
