A2-187 Girodisc Audi 356mm Rear Rotors

A2-187 Girodisc Audi 356mm Rear Rotors These Girodisc 2-piece floating rear rotors are a direct replacement for the OEM 356x22mm rear rotors used on Audi C7 S6, S7, RS6, and RS7 models. Designed for serious enthusiasts and track-day drivers, they deliver exceptional braking performance while significantly reducing unsprung and rotational mass. The Girodisc system maintains the factory brake bias and ABS calibration, making it the ideal performance replacement for stock discs. The 2-piece design allows the rotor rings to expand independently from the aluminum hats, improving heat dissipation and reducing stress-related cracking under repeated high-temperature conditions. Advanced Construction Each rotor ring is machined from Girodisc’s proprietary high-carbon iron alloy, developed for exceptional thermal stability, durability, and friction consistency. The 48 curved directional vanes work as internal air pumps to cool the rotor efficiently under load. The hats are CNC-machined from 606
