Brembo 08-17 S5 Front GT BBK 6 Piston Cast 380x34 2pc Rotor Slotted Type3-Fluo. Yellow

If you're looking to significantly upgrade your Audi S5's stopping power for spirited driving or track days, this Brembo GT Big Brake Kit is a serious consideration. This kit replaces your factory front brake setup with a much larger and more capable system, designed to handle the heat and stress of demanding use. It's built around a robust 6-piston caliper and a substantial 380x34mm two-piece rotor, offering a much larger swept area and greater thermal mass than stock.

The calipers themselves are cast from high-strength aluminum, a common choice for performance applications because it offers a good balance of strength and light weight. They feature a 6-piston design, which distributes braking force more evenly across the larger pad surface, leading to more consistent and powerful braking. The rotors are a two-piece design, meaning the rotor ring is separate from the hat. This construction helps manage heat expansion and can make replacement easier down the line. These rotors are slotted with Brembo's Type 3 pattern, which helps to vent gases and dust away from the pad surface, maintaining consistent grip even under heavy braking. The calipers are finished in a bright Fluorescent Yellow, adding a striking visual element to your wheels.

This kit is designed as a complete front brake upgrade. It includes everything you need to replace your factory front brakes with this high-performance system. When installing a kit of this caliber, it's always a good idea to have fresh brake fluid on hand, and consider a performance brake fluid that can handle higher temperatures. You'll also want to ensure your wheels have enough clearance for the larger caliper and rotor assembly; Brembo typically provides detailed clearance diagrams for their kits.
