Correct fitment depends on the brake package your car left the factory with (rotor diameter, iron vs. PCCB / carbon-ceramic, caliper colour). If you are unsure, contact PHD Racing with your VIN before ordering and we will confirm the part number.
Girodisc 2-piece floating rotors
- Iron friction ring on a 6061-T6 aluminum hat – cuts unsprung and rotating weight vs. the one-piece factory disc.
- Curved, directional cooling vanes act as a centrifugal pump, pulling air through the disc under repeated hard stops.
- Pin-drive float system with anti-noise spring washers: the ring grows with heat and self-centers without the cold rattle of a race-style floating rotor.
- Rings cast from Girodisc's own high-carbon iron and machined in-house in Bellingham, WA; hats machined from US-sourced aluminum.
- Keeps the factory calipers, brake bias and ABS behaviour. Sold in pairs, directional (left/right).
- Serviceable: when the rings wear out, order the Replacement rings only variant and keep your Girodisc hats. Replacement rings fit Girodisc hats only.
