The Girodisc A2-155 Rear Brake Rotors are a game-changer for Porsche enthusiasts seeking to enhance the braking performance of their 981 Cayman GT4, 718 Cayman GT4, and 991 Turbo/Turbo S models. These high-performance rotors are designed to replace the OEM steel rotors and offer significant advantages in both weight and performance.

Key Features and Specifications

The Girodisc system includes 380mm two-piece steel discs and aluminum hats, providing a lightweight yet durable solution for your rear brakes. The two-piece floating rotor design allows for direct bolt-on compatibility with your Porsche's OEM calipers, using included machined aluminum spacers. This setup ensures a seamless integration with the factory brake bias and ABS effectiveness. The rotors are made from 6061-T6 aircraft aluminum for the central hat and cast iron for the disc, with a curved-vane design that acts as a centrifugal pump to enhance cooling. The floating mount system uses ten cadmium-plated, high-strength alloy steel drive pins, ensuring a robust and quiet operation.

Practical Benefits and Target Audience

These rotors are ideal for drivers who demand both performance and reliability. By reducing rotational and unsprung mass, Girodisc rotors offer improved braking power and faster suspension response, making them perfect for high-performance driving and track days. When paired with racing brake pads and high-performance brake fluid, these rotors provide the ultimate solution for overheated and cracked OEM rotors. Their design allows for disc-only replacement, reusing the hat to minimize maintenance costs. Whether you're a track enthusiast or a daily driver, the Girodisc A2-155 Rear Brake Rotors are a smart investment for anyone looking to upgrade their Porsche's braking system.
