GiroDisc Porsche 911 Carrera (997.2) Slotted Rear Rings

GiroDisc is known for making well-built brake components that perform well under demanding conditions. For your Porsche 911 Carrera (997.2), these rear slotted rotor rings are designed to help your braking system work more effectively, especially when you're pushing the car hard. They replace the factory rotor rings, allowing you to keep your original brake hats, which can save you some money and make installation a bit simpler.

These rings are made from a high-carbon iron alloy, which is a strong material that can handle the heat generated during braking. The slots machined into the rotor surface are not just for looks; they help to vent gases and heat away from the brake pad surface. This means you get a more consistent and reliable grip, reducing the chance of brake fade when you need to stop quickly. The slot pattern is also designed to help keep the rotor surface cleaner, which can contribute to better pad life and more even wear over time. GiroDisc uses a two-piece design with these rings, which helps to manage thermal expansion and can reduce the risk of rotor warping compared to a solid one-piece rotor.

When installing these, you'll be reusing your existing brake hats. Make sure to thoroughly clean the hats and the mounting surfaces of the new rings before assembly. It's also a good idea to check the condition of your brake pads and any other brake hardware while you have the system apart. These rings are a solid option if you're looking to improve your car's braking performance and are comfortable with a two-piece rotor setup.
