Steeda is proud to offer their new 2-piece Full Floating Front and Rear Disc Brake Rotors for your Performance Pack-equipped EcoBoost or base GT 2015-2021 S550 Ford Mustang! These two-piece rotors are a simple bolt-on that’s ABS compatible with the factory front calipers, and Integrated Parking Brake Ford factory rear calipers. The 352 x 32mm front 15 rotors( 555 6036 ) weigh 7 pounds per pair less than OE solid 1-piece front discs, while the 330 x 25mm rears ( 555 6033 ) are 4 pounds per pair less than OE.

The billet, hard-anodized aluminum center section cuts weight and keeps wheel bearings cooler. Additionally, the high-ferrous-content, iron-alloy friction discs provide higher strength as well as a greater friction coefficient. A proprietary CNC-machined slotted groove pattern keeps pads cleaner and allows outgassing for maximum grip without glazing. A unique directional vent design draws more air through the rotor core for improved cooling, stable disc temps, and a significant reduction in peak operating temperatures.

The full floating design allows for both radial and axial expansion due to differing coefficients of thermal expansion between the aluminum hat and iron friction disc. This eliminates cracks common with 1-piece and drilled rotors on the market. Axial floatation vastly improves brake pedal feedback due to a reduction in vibration and pad knock. While conducting rigorous on-track testing, Steeda’s validation team measured up to 200 F temp reduction during the most severe conditions practical, with virtually no brake fade. Post-track inspection after multiple trials revealed no warping, cracking, or degradation in stopping performance or manners. During timed trials, the Steeda team pushed their test mule to the limit, resulting in incredible reductions in lap times, not only from stopping improvement but also handling and speed gains attributed to the reduction of both unsprung weight and rotating mass. Team Steeda tried to kill these rotors and the rotors won.

With exceptional quality & performance at an affordable price, these rotors are perfectly suited for daily driven pony cars, weekend canyon carvers, autocross racers, or full on competition track cars.

NOTE: Steeda has service kits available allowing you to rebuild your old rotors to like new condition and save money in the process. Each service kit includes left and right friction discs as well as all new premium grade hardware.
