Product Details

135/BMW Performance brakes for your E39 525i/528i/530i/540i! This kit uses the factory BMW Performance Brembo 6-piston calipers (same as 135i) with 135-sized rotors (338x26mm / 13.3") for a bolt-on braking upgrade. Everything comes complete - 6-piston calipers, rotors, custom caliper brackets, brake lines, and a pad sensor. Choose your preferred brake fluid and brake pads below (or call us for a recommendation).

Brake rotor options -

  • Zimmermann Coated - blank rotors with anti-corrosion coating
  • Turner/Centric slotted
  • Turner/Cetnric cross-drilled & slotted
  • BMW Peformance floating and cross-drilled
  • ECS 2-piece floating with cross-drilled and slotted

Brake pad options -

  • OEM Textar (same as stock 135i)
  • Centric Posi-Quiet - nearly dust-free (Turner preferred!)
  • Hawk Ceramic nearly dust-free
  • Hawk HPS performance
  • StopTech performance

This is a direct fit for all non-M E39 models and comes with a lot more braking power than standard. Consequently, there will be more front brake bias - the front brakes have more bite than before. During normal street driving, all you will notice is that the brakes feel stronger. For track driving, we recommend a more aggressive rear pad to balance the brake bias or a StopTech or Brembo big brake kit that has been properly engineered for the chassis (not a retrofit).

Requires 17" wheels and wheel spacers may be required depending on wheel spoke design. Most, but not all 17” wheels will clear these calipers. To verify fitment, please see the attached template.
