Girodisc Brake Rotors

Girodisc is an American company specialising in two-piece floating brake rotors for sports cars, supercars and track cars. Each rotor combines a cast iron friction ring with curved internal vanes and a 6061-T6 aluminium hat, joined by floating steel drive pins.

The Girodisc story. The company was founded in 2003 in Costa Mesa, California, with a clear goal: to design two-piece brake rotors that perform flawlessly at the limit, in a field where the rotor was often the overlooked link of the braking system. The first product sold, in 2004, was a rotor for the Ferrari 360. In 2007 Girodisc moved to Bellingham, Washington; in 2010 it brought manufacturing in-house and since 2012 it has poured its own raw castings in the USA. In 2019 it opened its new facility of around 1,600 square metres, with a dedicated brake dynamometer and a 75 kW solar array, and it uses only raw materials from American suppliers.

Specialising in floating rotors allows Girodisc to get the most out of the factory brake system: its rotors are quiet on the street and ready for the track, and for many enthusiasts they are a simpler and cheaper alternative to a big brake kit.

They are the ideal choice for anyone taking their car to track days and for drivers who want more from their braking system than the original rotors can give: consistent braking lap after lap, fewer overheating issues and easier maintenance, since over time only the friction rings need replacing.

The result is a rotor that sheds heat better, warps less during track sessions and weighs less than the original. When the ring reaches its minimum thickness, only the friction ring is replaced and the hat is reused. Girodisc also makes kits to switch from factory carbon-ceramic rotors to iron rotors, a popular choice for cars used on track.

All rotors are sold as a pair per axle, complete with hats, and for every application you will also find the matching pair of replacement rings.
