GIRODISC A1-276 Front Brake Rotor Kit 410 mm (Iron/PCCB) for PORSCHE 911 (992) GT3/GT3 RS

The Girodisc A1-276 is a 410 mm front brake rotor kit designed for the Porsche 911 (992) GT3 and GT3 RS, serving as a direct replacement for OE PCCB rotors. Made in the USA, this two-piece system features a proprietary cast iron disc and 6061-T6 aluminum hat. Curved vane internals and slotted faces maximize cooling and performance. A floating mount system with anti-noise washers reduces vibration and allows thermal expansion without sacrificing durability or alignment. A high-performance solution for track and street use with greater pad flexibility and reduced rotor weight.
