What is the benefit of the slotted design on these rotors?

The slots on these GiroDisc rotors help to sweep away brake dust and gases that can accumulate between the pad and rotor surface. This action helps to maintain consistent braking performance and prevent glazing of the pads.

Are these rotors compatible with the standard iron brakes on a 991.2 Carrera?

No, these specific rotors (A1-156) are designed for the Porsche 911 Carrera (991.2) models equipped with the Porsche Ceramic Composite Brakes (PCCB) and are made to work with the iron rotor pad shape. They are not intended for vehicles with standard iron brake systems.

What is a floating rotor design and why is it important?

A floating rotor design allows the rotor disc to expand and contract independently of the hub assembly as it heats up and cools down. This helps to prevent rotor warping and cracking, which can occur under the extreme thermal stress of hard braking.

Product Details

GiroDisc is well-known for making high-performance braking components, and these slotted front rotors for the Porsche 911 Carrera (991.2) with PCCB are a prime example. If you're looking to maintain or improve the stopping power on your specific 991.2 Carrera equipped with the Porsche Ceramic Composite Brakes (PCCB), these rotors are designed to work with the iron rotor pad shape, offering a direct replacement for your factory components.

These rotors feature a unique slot pattern that helps to sweep away dust and gas that can build up between the pad and rotor surface. This slotting is crucial for maintaining consistent braking performance, especially during repeated hard stops. The rotors themselves are constructed from a high-carbon, iron alloy, which is a strong material chosen for its ability to handle the heat generated during intense braking. GiroDisc also uses a floating rotor design, which allows the rotor to expand and contract independently of the hub assembly. This helps to prevent rotor warping and cracking under extreme thermal stress, a common issue with high-performance driving.

When installing these rotors, it's important to note that they are designed to be a direct fit for your 991.2 Carrera with PCCB, utilizing the iron rotor pad shape. This means no modifications are typically needed for installation, making it a straightforward process for a qualified mechanic. While these rotors are built for performance, they are also intended to provide a solid option for daily driving, offering a balance of durability and track-ready capability.
