Brembo 87-91 928 S4/GT Front GT BBK 4 Piston Cast 2pc 355x32 2pc Rotor Drilled-Black

The 355x32mm two-piece rotors in this Brembo Big Brake Kit are cast iron, chosen for their ability to handle significant heat without warping. This kit is specifically designed for the front of your 1987-1991 Porsche 928 S4 or GT, aiming to significantly improve your braking performance. The larger rotor surface area and the robust four-piston calipers work together to provide more consistent stopping power, especially during repeated hard braking events.

Brembo's GT Big Brake Kit includes everything you need to upgrade your front braking system. The calipers are a four-piston design, offering increased clamping force over stock calipers. The two-piece rotor construction, featuring a cast iron friction ring bolted to an aluminum hat, helps to reduce unsprung weight and manage heat more effectively. The rotors are drilled, which helps to dissipate heat and gasses, contributing to better performance and preventing fade. This kit is a substantial upgrade for drivers who demand more from their braking system, offering a noticeable difference in feel and capability.

When installing this kit, you'll want to ensure you have the correct tools and refer to the manufacturer's installation instructions for proper fitment and setup. Because this is a significant brake system upgrade, it's often recommended to consider matching the rear brakes for a balanced system, though this kit focuses on the front axle's performance needs. The black finish on the calipers and the drilled rotors give your vehicle a distinct, performance-oriented look behind the wheels.
