Brembo 08-17 S5/09-16 S4 Rear GTR BBK 4 Piston Billet 380x28 2pc Rotor Drilled- Nickel

The 380x28mm, two-piece rotor design in this Brembo GTR Big Brake Kit is a key feature for managing heat during aggressive driving. This kit is built around a set of four-piston billet aluminum calipers, chosen for their strength and light weight, which are crucial for reducing unsprung mass and improving suspension response. The rotors themselves are drilled for better heat dissipation and feature a nickel finish to help resist corrosion, keeping them looking good and performing well even after hard use.

When you're pushing your S5 or S4 to its limits, especially on track or during spirited canyon runs, the braking system is under immense stress. This Brembo kit addresses that by providing a significant upgrade over the factory setup. The larger rotor surface area combined with the multi-piston caliper design means more clamping force and better heat handling, which translates to more consistent stopping power and reduced brake fade. The billet construction of the calipers ensures they can withstand the rigors of high-performance driving without flexing, maintaining pedal feel and control.

This kit is designed to be a comprehensive upgrade for the rear of your vehicle. It includes everything needed to install the new calipers and rotors, ensuring a direct fitment for the specified Audi models. While installation is straightforward for a performance brake kit, it's always a good idea to consult the manufacturer's instructions or a professional mechanic to ensure proper setup and bleeding of the brake system. The result is a braking system that not only looks impressive behind the wheels but also offers a substantial improvement in performance and driver confidence.
