Girodisc Porsche 996 GT3 Cup Rear Rotors (with Spacers & Bolts) The Girodisc A2-126B Rear Rotor Kit is a high-performance, direct replacement solution for Porsche 996 GT3 Cup models, as well as 997.2 GT3 and GT2 variants. Designed to work seamlessly with OEM calipers and unmodified factory pads, this 2-piece floating rotor system enhances braking performance and cooling without altering factory brake bias or ABS operation. Lightweight, High-Performance Design Each Girodisc rotor assembly features a precision-machined 6061-T6 aluminum hat mated to a proprietary cast iron rotor ring. The 2-piece design reduces unsprung and rotational mass, allowing for faster suspension response, better braking consistency, and improved acceleration.
