GiroDisc Porsche 911 GT3/GT3RS/GT2RS (991 Excl PCCB) Slotted Rear Rings

This product includes a pair of GiroDisc slotted rear rotor rings, designed specifically for the Porsche 911 GT3, GT3RS, and GT2RS models from the 991 generation, excluding those equipped with Porsche Ceramic Composite Brakes (PCCB). These are replacement rings that mount to your existing GiroDisc or OEM rotor hats, offering a way to refresh your braking system without replacing the entire rotor assembly. They are intended for owners who want to maintain or improve their high-performance braking capabilities.

GiroDisc is known for making well-built brake components, and these rotor rings are no exception. They are made from a high-carbon iron alloy, which is a strong material that holds up well under the heat generated during spirited driving and track use. The slots machined into the rotor surface are a key feature. They help to sweep away brake dust and gasses that can build up between the pad and the rotor surface. This action helps to keep the braking surface clean, which leads to more consistent stopping power and can also help reduce brake fade, especially during demanding driving conditions. The rings are designed to be a direct replacement for the original rings, making the installation process straightforward for someone familiar with brake work.

When installing these rotor rings, you'll be mounting them to your existing rotor hats. Ensure that both the hat and the new ring are clean and free of debris before assembly. This is a common service for high-performance vehicles that see frequent track use or aggressive street driving, allowing you to replace worn rotor surfaces while keeping your original, often expensive, rotor hats. Refer to the manufacturer's installation instructions for specific details on assembly and torque specifications.
