Product Details

Improves braking performance, handling response, and acceleration. An all-around upgrade in chassis dynamics.

Reduce heat. Reduce warping. Increase Performance!

ECS Tuning engineered 2-Piece semi-floating rotors offer real world benefits that can be felt on both the street and track! Our 2-Piece rotors combine the advantages of weight savings and rapid heat dissipation to provide a rotor superior to stock while preventing warping and extending component life. The reduction of unsprung weight improves handling characteristics under all situations. This reduction in rotational inertia allows for quicker acceleration, decreased braking distances, and more responsive handling. By using our front ECS 2-Piece rotors you save 2 lbs per axle than going with the genuine BMW rotor.

Features include:

  • Aluminum hats: To save weight, each rotor ring is bolted to a lightweight aluminum hat made from high quality 6061 aluminum, and hard anodized with an attractive matte black finish that is both durable and corrosion resistant.
  • Gray cast iron rings: Long known for its wear resistance and stable friction characteristics, cast iron is favored for brake rotors due to its ability to absorb and dissipate large amounts of heat.
  • 2-Piece construction: Conventional rotors are unable to cope with the stress of drastic heat fluctuations and are prone to warping. ECS 2-Piece semi-floating rotors allow the radial expansion of the rotor ring - preventing warping.
  • Heat treated: Heat treating of ECS 2-Piece rotors makes them stiffer and stronger - for improved performance and further prevention of warping.
  • Drilled and slotted: 2-Piece rotors are cross drilled to promote cross ventilation for improved cooling as well as slotted to clean brake pads and carry away water and brake dust. Cleaner brake pads result in faster, more consistent stopping. Drilled holes are chamfered while slots are machined with a ball end mill - both to prevent cracking that may be present on improperly machined rotors.

 

  • Manufacturing quality: Non-friction ring surfaces, including internal vents, are painted to resist salt and other corrosives. Ground braking surfaces ensure rings run parallel, and pads bed easily.
  • Includes ECS Stainless Rotor Set Screws to eliminate rusty factory fasteners
