Girodisc Porsche 996 / 997 Rear Rotors (with Spacers & Bolts)
The Girodisc A2-032A Rear Rotor Kit is a precision-engineered performance upgrade for Porsche 996 and 997 models. Designed as a direct-fit replacement for the OE rotors, this 2-piece system includes caliper spacers and longer bolts to accommodate the larger 350mm rotor size—delivering improved braking torque, heat capacity, and cooling efficiency without altering factory bias or ABS operation.
Enhanced Performance & Lightweight Design
Each rotor assembly features a 6061-T6 aluminum hat mated to Girodisc’s proprietary cast iron rotor ring. This 2-piece configuration significantly reduces unsprung weight while maintaining strength and durability. The curved internal vane design acts as a centrifugal pump, pulling air through the disc to increase cooling capacity during high-performance driving. The result is sharper braking response and reduced fade under repeated heavy use.
Floating Mount System & Anti-Noise Technology
Girodisc rotors use a floating mount system with 10 high-strength alloy steel drive pins manufactured in-house in the USA. The pins are cadmium-plated for corrosion resistance and secured by class 12.9 cap screws with hardened washers. Anti-noise spring washers on the rotor side prevent rattling, allowing for quiet street operation while maintaining full racing functionality. This float design lets the rotor self-center between pads and expand with heat for consistent braking performance.

Engineered for Porsche Precision
The Girodisc system replaces the factory rotor with a larger, two-piece floating design engineered for performance and longevity. Each assembly pairs a CNC-machined 6061-T6 aluminum hat with Girodisc’s proprietary cast-iron friction rings, both made in the USA. The curved internal vane structure acts as a centrifugal pump, forcing air through the rotor for enhanced cooling. With its increased rotor size and floating design, this upgrade delivers superior heat management and more consistent braking under repeated high-speed stops.
