Girodisc A2-032B 350mm 2pc Porsche Rear Rotors
$1,922.00
Girodisc 350mm Porsche 996 / 991 / 992 Rear Rotors (with Spacers & Bolts)
The Girodisc A2-032B Rear Rotor Kit is a premium direct-fit replacement for Porsche 996, 991, and 992 models. Engineered for high-performance driving, this system includes caliper spacers and longer bolts to accommodate the larger 350mm rotors. The result is improved braking torque, enhanced cooling efficiency, and reduced unsprung mass—all while retaining factory fitment and ABS calibration.
Lightweight Design & Increased Performance
Each Girodisc rotor assembly pairs a CNC-machined 6061-T6 aluminum hat with a proprietary cast iron disc. The 2-piece design significantly reduces rotational mass compared to OEM rotors, improving suspension response and acceleration. The curved vane design acts as a centrifugal pump, drawing air through the rotor to enhance cooling and resist fade under extreme braking conditions.
Precision Floating Mount System
The rotors feature Girodisc’s race-proven floating mount design with 10 cadmium-plated steel drive pins connecting the iron ring to the aluminum hat. These pins allow the disc to expand radially under high temperatures without warping, ensuring consistent pad contact. Anti-noise spring washers eliminate rattle, maintaining quiet operation suitable for street and track use alike.

The GiroDisc replacement rotor system is a direct rotor disc replacement for the Giro Disc 2-piece hat and rotor and no modifications are necessary.
The rotor and hat mount together through a floating mount system which utilizes 8-10 high strength alloy steel drive pins manufactured by GiroDisc in the USA to our own specifications and are cadmium plated for corrosion resistance. The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. The pins are secured by grade12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors.
The 2-piece GiroDisc design allows for rotor only replacement to minimize replacement costs and deliver outstanding performance and cooling.

PFC 11 Compound
A new generation sprint and medium distance friction: the ultimate in control with superior disc conditioning. Developed from 01 compound with improved bite, modulation, and release characteristics. It is ultra smooth and developed to reduce wheel locking at the end of braking while giving more cold and hot bite than the endurance oriented 08 compound. Brake with confidence; brake with ultimate control and modulation.
PFC 08 Compound
One of PFC's most popular compounds which came to fame in Endurance Sportscar and GT racing due to its performance in applications where smooth initial bite is a must. PFC08 has a slight friction rise with temperature, excellent release and modulation characteristics. Despite its considerable performance, 08 has the lowest wear rate of all PFC compounds and can easily match the wear characteristics of the other competitors' materials but with much higher bite and consistent performance across a broad temperature range.
