Please ensure your correct model is selected

Similarly to brake pads, the brake rotors can be matched to specific driving conditions and intended use. For solely street use the design and characteristics particular to each rotor are not big factors in overall braking performance. For instance, a cross-drilled rotor will not significantly improve braking under street conditions. Improved stopping performance will come mostly from your brake pads. Some rotor designs perform better under racing conditions with racing pads but, generally, all rotor types can be used on the street. For race track use we typically recommend a slotted or blank stock rotor. Any 2-piece floating rotor is superior to anything else and those are our first recommendation when available. For more information on the brake rotors we sell, check out our rotor buying guide.

All of these rotors are manufactured to meet BMW's specs for each vehicle application. Our standard rotors are sourced from original manufacturers for BMW (OEM), performance alternatives, or straight from BMW themselves. In some cases BMW Motorsport and BMW Performance will have their own rotor upgrades. Our Cross-Drilled, Slotted, and Drilled+Slotted rotors are manufacturered by StopTech - a global leader in braking technology and the braking technical partner to the Turner Motorsport racing team.

These 2-piece floating rotors help dissipate heat better than a standard cast iron rotor and are also lighter for less unsprung weight. Managing heat in the brake system is vital to braking performance, especially on the track or when driven hard. It's why your brake rotors have internal vanes that vent heat as the rotor spins. These 2-piece ECS rotors feature an outer cast iron friction surface ring that is separate from the aluminum center hat. This allows better airflow through the vanes and for the friction ring can expand as it gets hot. The rotors are also cross-drilled for better ventilation and slotted to improve brake pad performance.

ECS 2-Piece Rotors feature:

  • Aluminum hats for light weight
  • Heat-treated cast iron friction rings
  • 2-piece assembly improves brake cooling
  • Anti-corrosion coating on non-friction surfaces and hard anodizing on rotor hat

These are the same size as the stock rotors so your stock caliper and mounting bracket will fit and there will be no clearance issues with your wheels or to other components. Stainless steel rotor retaining screws are included. You can use these with any brake pad.

Price is for the pair of brake rotors.

This item fits the following BMWs:
2001-2006 E46 BMW M3 with CSL or ZCP brakes
2006-2008 E85 E86 BMW Z4 M Coupe Z4 M Roadster
