Brembo 00-02 S4/02-05 A4/06-08 A4 Front GTS BBK 4 Piston Cast 365x29 2pc Rotor Drilled-Black HA

If you're looking to significantly upgrade your Audi S4 or A4's braking performance, this Brembo Big Brake Kit (BBK) is designed for that purpose. This kit replaces your factory front brake setup with a much larger and more capable system, built to handle the demands of spirited driving and track use. It's a comprehensive solution for drivers who want a noticeable improvement in stopping power and fade resistance.

At the heart of this kit are the four-piston aluminum calipers, which offer increased clamping force over stock. These calipers work with substantial 365x29mm two-piece rotors. The two-piece design helps manage heat by allowing the rotor and hat to expand independently, reducing the risk of warping. The rotors themselves are drilled, which helps with initial bite and can assist in clearing out dust and gas under hard braking conditions, maintaining consistent performance. The black finish on the caliper housing adds a clean, performance-oriented look behind your wheels.

This Brembo BBK is a substantial upgrade, and it's important to note that it's designed as a complete front brake system replacement. Ensure you have adequate clearance for the larger calipers and rotors within your current wheel setup. For optimal performance and longevity, it's recommended to follow the manufacturer's installation and bedding-in procedures carefully. This kit represents a significant investment in your vehicle's braking capability, offering a well-built and proven solution from a respected name in performance braking.
