GiroDisc Rotors & Brake Parts

GiroDisc is a U.S.-based manufacturer of high-performance brake parts, specializing in two-piece floating brake rotors. Compared to the traditional one-piece design, these rotors run cooler and have lighter construction, helping reduce unsprung weight. Each rotor weighs 4-8 pounds less than the original, further improving braking efficiency and reducing the stress on the suspension. GiroDisc rotors provide a solid improvement in stopping power without the complexity and expense of a complete big brake kit.

GiroDisc brake rotors have a clever tension hardware system that keeps them quiet for daily driving while maintaining the performance you need when pushing your car to its limits on track days. The company takes a made-in-America approach, using U.S.-sourced materials and handling everything from design to manufacturing at its facility in Bellingham, Washington.

The center hat is made from 6061-T6 aircraft-grade aluminum, chosen for its excellent strength-to-weight ratio. The cast iron rotor section uses the same high-spec material you'll find in professional racing, with curved vanes that act like a pump, pulling cool air through the rotor to keep it from overheating. What makes GiroDisc special is the floating mount system that connects the rotor and hat. They use tough alloy steel drive pins, coated to resist rust, to handle the force of braking while letting the rotor expand and move slightly as it heats up. They've solved the typical floating rotor rattle issue with anti-noise spring clips, so you get the performance benefits without the annoying noise that often plagues other floating designs.
