Bring modern performance and race-proven engineering to your Audi B7 RS4 with Girodisc’s lightweight two-piece rear rotors.

Vehicle Fitment
Audi RS4 (B7, 2006–2008)
Compatible with OEM rear calipers and factory hardware.
Precision-Crafted Braking Performance
The Girodisc system installs directly onto factory hubs—no modifications required. Each rotor combines a CNC-machined 6061-T6 aluminum hat with Girodisc’s proprietary cast-iron friction ring, both designed and machined in the USA. The floating two-piece construction allows for independent thermal expansion between the rotor and hat, preventing warping and maintaining consistent pedal feel. Curved internal vanes act as centrifugal pumps to draw air through the disc, enhancing cooling and stability during aggressive driving or track use.
