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.

Our in-house engineered TrackSport rotors feature a full floating two-piece design and slotted grooves to allow smooth, consistent braking force and easy expulsion of gases and dust created by the brake pads and rotors under heavy braking. This means that no matter the conditions, you can expect the braking feel to remain consistent, even throughout long periods of abuse. When considering a brake rotor upgrade, it's important to factor in their specific use. On the road, a solid rotor is a simple, yet cheap and effective solution that is perfectly capable of handling daily-driver requirements. When you start taking your BMW to the track, things become a little more complicated. Extended periods of aggressive driving causes the amount of heat in the rotors to build up, and as the temperature of the rotors increase, the metal begins to expand. With solid rotors, this can lead to numerous issues such as warping of the rotors, unexpected cracking along the inner "ring" or friction surfaces, and increased brake fade.
