Brembo 87-91 928 S4/GT Front GT BBK 4 Piston Cast 2pc 355x32 2pc Rotor Slotted Type-1-Red

If you're looking to significantly improve the stopping power and feel of your 1987-1991 Porsche 928 S4 or GT, this Brembo GT Big Brake Kit is a serious upgrade. This kit replaces your factory front brakes with a much larger and more capable system, designed to handle the demands of spirited driving and track use. You'll notice a substantial difference in pedal feel and fade resistance, even during repeated hard stops.

At the heart of this kit are the massive 355x32mm two-piece rotors. The two-piece design helps manage heat more effectively than a single-piece rotor, and the slotted surface helps clear away brake dust and gases, ensuring consistent contact between the pad and rotor. These rotors are paired with robust 4-piston aluminum calipers, which apply more even pressure across the pad surface for improved braking force. The calipers are finished in a striking red, adding a performance look to your front end. This kit is a well-built system from Brembo, a name trusted in high-performance braking for decades.

This kit includes everything you need to get your 928's front brakes converted to this high-performance setup. You'll receive the calipers, rotors, mounting brackets, and the necessary hardware to complete the installation. While this is a bolt-on kit, it's a complex job that requires careful attention to detail. We recommend consulting the manufacturer's installation guide for specific instructions and torque specifications.
