What material are these GiroDisc rotor rings made from?

These rotor rings are made from a high-carbon iron alloy. This material is chosen for its good thermal stability and resistance to wear, which are important characteristics for high-performance brake components.

Do these rotor rings come with new rotor hats?

No, these are replacement rotor rings only. You will need to reuse your vehicle's original rotor hats and associated hardware during the installation process.

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

The slots machined into the braking surface help to evacuate brake dust, gases, and heat away from the pad and rotor interface. This can lead to more consistent braking performance, especially under heavy use, and can also help keep the rotor surface cleaner.

About this part

Product Details

GiroDisc is well-known for making high-performance brake components, and these slotted front rotor rings for the Porsche 911 GT3 and GT2 (specifically the 997.2 models, excluding those with PCCB ceramic brakes) are a prime example of their work. If you're looking to upgrade your braking system for more demanding driving, these rings are designed to offer improved performance and durability over stock components.

These rotor rings are constructed from a high-carbon iron alloy, which is a solid choice for brake components because it offers good thermal stability and wear resistance. The rings are slotted, meaning they have machined grooves on the braking surface. These slots help to vent gases and heat away from the pad surface, which can lead to more consistent braking performance, especially during repeated hard stops. This design also helps to keep the rotor surface cleaner, which can improve pad life. The rings are designed to be a direct replacement for your original front rotors, making the installation process more straightforward, assuming you are comfortable with brake system work. You will need to reuse your existing rotor hats and hardware for this installation.

When considering a brake upgrade like this, it's important to ensure you have the right components for your specific vehicle. These rings are made for the 997.2 generation Porsche 911 GT3 and GT2 models that do not come equipped with the factory Porsche Ceramic Composite Brakes (PCCB). Make sure to verify your vehicle's original brake setup before ordering.
