Product Description

The GiroDisc A2-152 is a rear 2-piece slotted rotor set built as a direct bolt-on replacement for the 2009-2014 Audi TT RS Mk2, working with factory calipers with no modification needed. The cast iron disc rides on a 6061-T6 aluminum hat, shaving about 1.8 lbs per corner compared to the stock rotor.

A floating pin mount lets the disc self-center and expand with heat without the noise typical of some floating rotors, while the curved vane design pulls cooling air through under braking. Once the rotor wears down to its 20mm minimum thickness, only the cast iron ring needs replacing - the aluminum hat can be reused, keeping long-term maintenance costs down. Factory electronic parking brake function is retained where equipped.
