GiroDisc 2017+ Audi RS4/RS5 (B9) Slotted Front Rings

GiroDisc is well-known for making high-performance brake components, and these slotted front rotor rings for your 2017 and newer Audi RS4 or RS5 (B9 chassis) are a prime example. If you're looking to improve your braking performance, especially under demanding conditions, these rings are designed to work with your existing factory iron hats, making them a direct replacement for the original rotors. This means you get an upgraded braking surface without needing to replace the entire rotor assembly, saving you time and money on installation.

These rings are constructed from a high-carbon iron alloy, which is a solid choice for brake rotors because it offers good thermal capacity and wear resistance. The key feature here is the slotting pattern. GiroDisc's specific slot design helps to sweep away dust and gas that can build up between the pad and the rotor surface. This action keeps the pad surface cleaner and cooler, leading to more consistent braking performance, especially during repeated hard stops where heat can become a major issue. The slots also help to deglaze the rotor surface if it becomes contaminated, ensuring a fresh braking surface is always available.

When you're ready to install these, you'll be able to use your factory caliper carriers and brake pads. The rings are designed to be a direct fit onto your existing rotor hats, which are typically made of aluminum. This design approach allows for easier maintenance and replacement down the road, as you only need to replace the friction rings when they wear out, rather than the entire rotor assembly. This makes them a practical choice for drivers who push their cars hard and want a reliable braking upgrade.
