EBC D1806 Rear Brake Rotors for BMW Z4 E89 with TRW Rear Calliper

Restore confident, smooth braking on your BMW Z4 E89 with the EBC D1806 rear rotors. Designed to match OEM geometry for the TRW rear calliper version, these coated stopping discs deliver refined pedal feel, consistent bite and dependable everyday performance. If you are searching for BMW Z4 back brakes, rear rotor kit, rust-resistant brake discs or TRW fitment rear rotors, this is the direct bolt-on choice that just works.

What makes D1806 a smart upgrade

  • G3000 grey cast iron - OE-matched material for stability, strength and heat control on the road.
  • Thermic Black anti-corrosion finish - helps resist rust on the non-friction areas for a clean, factory look longer.
  • Precision machining and dynamic balancing - quiet, vibration-free operation and confident stopping.
  • 100 percent runout checked - each rotor is inspected to help prevent judder and uneven wear from the start.
  • True bolt-on installation - built specifically for BMW E89 Z4 models using the TRW rear calliper.
  • Excellent pedal feel - OE-quality refinement with consistent, predictable braking in daily driving.
  • EBC Brakes warranty - one year or 10,000 miles. Manufacturer terms apply.

We use these discs on our own vehicles and fit them for customers - feedback has been consistently positive for road use, refinement and longevity. For best results, always install fresh pads with new discs and follow correct bedding-in procedures.
