Product Description

GiroDisc's 356mm rear rotor swaps the heavy factory single-piece rotor on the Audi C7 platform for a lighter, floating aluminum-hat/high-carbon-iron-disc assembly, cutting unsprung weight and rotating mass at the rear axle without touching factory brake bias or ABS calibration. The 48-vane design pulls air through the hub for meaningfully better cooling under sustained hard braking than the factory rotor.

Because the hat is reusable, replacing worn rotor rings down the road only requires the D2-187 ring set rather than a full rotor - a lower long-term cost for owners who track their C7 S6, S7, RS6, or RS7 regularly. Manufactured entirely in-house in the USA, it's a direct bolt-on with no modification to calipers or pads required.
