EBC Turbo Grooved GD Sport Rear Brake Discs 300x66mm for BMW 1 Series F20 F21 - Slotted Dimpled Performance Rotors, Gold Zinc Coated - Fast Road Upgrade, OEM Replacement 300mm Rear Rotors for BMW F20/F21 1 Series Hatchback

EBC slotted and dimpled rear rotors for BMW 1 Series F20 F21 - 300 x 66 mm, gold zinc coated

Give your BMW 1 Series the stopping confidence it deserves with these EBC performance rear discs. Precision machined with sweeping slots and blind dimples, they are a superb fast road upgrade that delivers stronger initial bite, better pedal modulation and reliable braking on spirited drives. The grooved face helps shed dust, water and debris for a clean contact patch, while the dimples aid pad de-gassing without compromising structural integrity.

We run these on our own cars and our customers consistently report cooler running and reduced fade compared with standard rear discs. The durable gold zinc finish protects the non-friction areas against corrosion, keeping the hubs and edges looking smart for longer in UK weather.

Key benefits

• Machined slots promote airflow across the face for improved heat management and fade resistance
• Blind dimples help vent hot gases to maintain consistent friction and confident pedal feel
• Slots reach the outer edge to sweep away dust and water for stable performance in wet conditions
• Encourages even pad wear for predictable braking and longer component life
• Gold zinc plating on non-swept areas adds corrosion protection and a premium look
• Direct replacement for the rear axle on suitable BMW 1 Series F20 and F21 models
