Product Details

Requires the use of 17" or larger wheels

Brake harder with less brake fade.

ECS Big Brake Kit includes:

  • 6-piston calipers from the E82, E88 and the E9X BMW Performance big brake kit, with original equipment pads

  • 325x25 semi-floating BMW Performance Rotors

  • ECS caliper brackets

  • ECS Exact Fit braided stainless reinforced brake lines

  • All necessary hardware, including pad sensor, caliper and carrier bolts, and rotor screws.

  • One liter Pentosin Super DOT4 Brake Fluid

Brake bias will not be dramatically affected. For track applications, a more aggressive rear pad is recommended. Most 17” wheels will clear these calipers. To verify fitment, please see the attached template.

The four (4) longer bolts pictured will come attached to the OEM caliper carrier. This carrier must be removed and replaced with the ECS caliper carrier. Please refer to the attached installation guide for further details.
