What is the main benefit of the slots on these rotors?

The slots help to vent brake dust and gases away from the pad surface. This keeps the pads cleaner and allows them to maintain consistent contact with the rotor, which improves braking performance and reduces fade.

Do these rotors come with new hardware?

This product listing is for the rotors only. It is recommended to inspect your existing brake hardware, including pads and any associated clips or shims, and replace them if necessary during installation.

Can I use these rotors with my standard brake pads?

Yes, these GiroDisc slotted rotors are designed to be compatible with most standard and performance brake pads for the specified Porsche models. However, always ensure your brake pads are in good condition and suitable for your driving needs.

Product Details

These are GiroDisc slotted rear brake rotors specifically made for the Porsche 911 Turbo and Turbo S models from the 991 generation, excluding those equipped with the Porsche Ceramic Composite Brakes (PCCB). If you're looking to improve your braking performance and feel, especially during spirited driving or track use, these rotors are a solid choice. They are designed to work with your car's existing brake system, offering a direct replacement for the factory rear rotors.

GiroDisc rotors are well-built with a focus on performance and durability. The slots machined into the rotor surface are not just for looks; they serve a crucial function. As the brake pads heat up and wear, they release gases and dust. These slots help to vent these gases and dust away from the pad surface, which means you get a more consistent and powerful bite from your brakes, even under heavy use. This can help reduce brake fade and improve overall stopping power. The rotors are made from a high-carbon iron alloy, which is known for its strength and ability to handle the heat generated during braking. This material choice helps ensure the rotors can withstand the demands of performance driving without premature wear or warping.

When installing these rotors, you'll be replacing your stock rear rotors. It's always a good idea to inspect your brake pads and hardware at the same time to ensure everything is in good condition. These rotors are designed to be a direct fit, meaning they should install without modification to your vehicle's brake system. If you're looking for an improved braking experience that offers better performance and feel, especially when pushing your 911 Turbo or Turbo S, these GiroDisc slotted rotors are a worthwhile consideration.
