A2-155 Girodisc 2pc Rear Brake Rotors Upgrade

The A2-155 Girodisc 2pc Rear Brake Rotors are a game-changer for Porsche enthusiasts seeking to enhance their vehicle's braking performance. This premium upgrade kit includes two lightweight, high-performance rear brake rotors designed to replace your OEM steel rotors. Crafted with precision, these rotors are engineered to bolt directly onto your Porsche 981 Cayman GT4, 718 Cayman GT4, or 991 Turbo/Turbo S, ensuring a seamless fit and optimal performance. The included machined aluminum spacers ensure compatibility with your OEM calipers, maintaining the factory brake bias and ABS effectiveness.

Technical Specifications and Advantages

The Girodisc system features a two-piece floating rotor design, which not only reduces rotational and unsprung mass but also enhances braking and suspension response. The central hat of the rotor is made from 6061-T6 aircraft aluminum, while the disc is manufactured in the USA from cast iron used by professional racing organizations. This curved-vane design, developed in racing, acts as a centrifugal pump, forcing cool air through the disc to dissipate heat effectively. The rotors are mounted through a floating mount system using ten cadmium-plated, high-strength alloy steel drive pins, ensuring durability and optimal performance. Anti-noise spring washers eliminate the noise typically associated with floating rotors, providing a quiet and smooth driving experience.

Applications and Benefits

Whether you're a track enthusiast or a daily driver, the A2-155 Girodisc Rear Brake Rotors offer numerous practical benefits. Paired with Pagid or PFC racing brake pads and Performance RF1 racing brake fluid, these rotors are the ultimate solution for overheated, cracked OEM Porsche rotors. Their lightweight design reduces unsprung mass, leading to faster suspension response and improved handling. The two-piece design allows for disc-only replacement, reusing the hat to minimize maintenance costs. This product is perfect for those who demand the best in performance, reliability, and aesthetics, ensuring a safe and enjoyable driving experience.
