GiroDisc Porsche 991 Cup/GT4 Clubsport Slotted Front Rings (For PFC/Porsche Hats)

These GiroDisc front rotor rings are made from a proprietary iron alloy, a material chosen for its ability to handle the intense heat generated during track driving without warping. They are specifically designed to be used with your existing PFC or factory Porsche brake hats, making them a cost-effective way to upgrade your braking system without replacing the entire rotor assembly. The slotted design is a key feature, helping to dissipate heat and gasses that build up between the pad and the rotor surface. This means you get more consistent braking performance, especially during repeated hard stops on the track.

GiroDisc has engineered these rings to be a direct replacement for the original rotor rings on your Porsche 991 Cup or GT4 Clubsport. The slots are precisely machined to help sweep away dust and debris, ensuring a clean surface for your brake pads to grip. This attention to detail helps maintain optimal friction and reduces the chance of glazing, which can happen with standard rotors under extreme conditions. When you're pushing your car hard, reliable braking is paramount, and these rotor rings are built to meet that demand.

To install these, you'll be replacing your current front rotor rings onto your existing PFC or Porsche brake hats. This process requires careful attention to detail and typically involves removing the caliper and wheel assembly. It's a job that many track-focused owners tackle themselves, but if you're not comfortable with brake work, it's always best to have a qualified mechanic handle the installation. Ensure you follow the manufacturer's recommended procedures for mounting the rings to the hats to maintain the integrity of the system.
