Product Overview

Looking for an all-around braking upgrade for your street or track E9X M3? Look no further than this comprehensive ECS performance braking kit.

For the front, ECS Tuning's E9X M3 big brake kit. Utilizing 6-piston F10 M5 brake calipers, this kit offers improved brake cooling and increased heat carry capacity with brake bias that is near identical to factory brake configuration - all while fitting under factory 19" wheels. 

Taken from the F10 M5 parts bin and adapted to the E9X M3 with proprietary brackets and rotors by ECS Tuning engineers, 6-piston Brembo calipers finished in blue with ///M logos do the clamp work. Massive 382x36mm ECS 2-piece rotors offer excellent cooling characteristics, with nearly a 50% increase in vein count and internal surface area. With ECS Exact-Fit Stainless Steel Brake Lines, all of the pressure applied by your right foot makes it's way to the wheels. Stainless steel braided lines do not expand under pressure as conventional rubber lines do, resulting in a decrease in pedal modulation and improvement in pedal feel.


  • 50% increase in brake cooling and heat carry capacities
  • Vivid blue calipers with ///M logos look fantastic behind any wheel
  • No modification to vehicle required - installation is as simple as a standard brake service and line replacement (see attached DIY install PDF for a step-by-step guide!)
  • Fits under factory 19" Style 219 front wheels (see attached wheel fitment template PDF to check fitment on other wheels)
  • A 5mm spacer is recommended for Factory 19" Style 359 wheels 

Includes, for the front:

  • Genuine F10 M5/Brembo 6-piston calipers
  • ECS Tuning 2-piece 382x36mm rotors
  • ECS Tuning Exact-Fit brake lines
  • ECS Tuning stainless steel rotor set screws
  • Pentosin Super DOT4 brake fluid
  • Hardware & pad wear sensors

For the rear, complementary lightweight ECS 2-piece rotors combined with Cool Carbon Performance brake pads offer excellent stopping power. Also includes rear and mid position ECS Exact-Fit brake lines. 

For the rear:

  • ECS Tuning 2-piece 350x24mm rotors
  • Cool Carbon Performance brake pads
  • ECS Tuning Exact-Fit brake lines

Front brake kit reuses factory brake dust shields; slight bending of caliper dust shields is required.

Bracket to knuckle: 110Nm
