GiroDisc 08-16 Audi S4/S5 (B8) Slotted Front Rotors

These GiroDisc front rotors feature a unique 2-piece floating design, with the rotor ring constructed from a high-carbon iron alloy. This construction is key to their performance, allowing the rotor ring to expand and contract freely with heat without transferring stress to the hat. The hat itself is machined from aircraft-grade 6061-T6 aluminum, which is not only strong but also significantly lighter than a traditional one-piece rotor. This reduction in unsprung weight can make a noticeable difference in how your car handles, especially during spirited driving or track use.

The rotor face is precision-machined with 60 directional slots. These slots are crucial for performance braking; they help to vent hot gases and dust away from the pad surface. This keeps the pads cleaner and cooler, which means more consistent stopping power, especially under heavy braking conditions where heat buildup can cause brake fade. The directional slotting is designed to work with the rotor's natural direction of rotation for optimal performance and to help reduce noise.

When you're looking to get the most out of your Audi S4 or S5 (B8 chassis), especially if you plan on doing track days or autocross events, these rotors are a solid choice. They are designed as a direct replacement for your factory front rotors, meaning installation is straightforward without needing any modifications. You'll notice improved braking feel and fade resistance when you push your car hard.
