In most spec racing series, teams are locked into stock one-piece brake rotors — but when the rules open up, serious competitors choose GiroDisc two-piece performance rotors. Designed for endurance, GT, and open-class racing, GiroDisc rotors deliver the cooling capacity, strength, and repeatability that stock components simply can’t match.
CNC-machined from high-carbon cast iron and paired with lightweight billet aluminum hats, GiroDisc rotors dramatically reduce un-sprung weight while improving thermal stability. The result is faster heat recovery, reduced fade over long stints, smoother pedal feel, and extended component life — exactly what pro-level teams demand during endurance races.
Whether you’re pushing through multi-hour events or running in an open class where every advantage counts, GiroDisc provides the stopping power, consistency, and durability required to compete at the highest levels.
