GiroDisc Porsche 911 GT3 Cup (997) Slotted Front Rings

This is a set of GiroDisc slotted front rotor rings specifically for the Porsche 911 GT3 Cup (997) model. These are designed as a direct replacement for your factory front rotors, meaning you can use your existing calipers and mounting hardware. If you're tracking your GT3 Cup or pushing it hard on the street, you know how important consistent braking performance is. These rings are built to handle the heat and stress of demanding driving.

GiroDisc uses a high-carbon iron alloy for the rotor rings themselves, which is known for its ability to withstand high temperatures without warping or cracking. The slots machined into the rotor surface are not just for looks; they serve a crucial purpose. As the brakes heat up, they generate gases and friction material dust. These slots help to vent these gases and dust away from the pad surface, which keeps the pads biting cleanly and consistently, even during prolonged hard braking. This improved cooling and gas evacuation means you get a more predictable and reliable pedal feel when you need it most.

These are sold as a pair of rings only, so you will need to transfer your existing aluminum rotor hats to these new iron rings. This process is straightforward for someone familiar with brake systems. By offering replacement rings, GiroDisc provides a cost-effective way to maintain peak braking performance without having to replace the entire rotor assembly each time. This setup is a popular choice for GT3 Cup owners looking for an upgrade that offers tangible benefits on the track and the street.
