Brembo 87-91 928 S4/GT Rear GT BBK 4 Piston Cast 2pc 328x28 2pc Rotor Drilled-Silver

This Brembo Big Brake Kit for the rear of your 1987-1991 Porsche 928 S4 and GT models features a 4-piston cast aluminum caliper paired with a 328x28mm two-piece rotor. The calipers are designed for robust stopping power, and the two-piece rotor construction helps manage heat more effectively than a traditional single-piece rotor. The drilled surface on the rotors aids in dissipating heat and gas, which can improve braking consistency during demanding use.

The kit includes Brembo's GT calipers, known for their solid construction and reliable performance. These calipers are paired with two-piece rotors, where the rotor disc is separate from the hat. This design allows for better thermal management and can reduce unsprung weight compared to a single-piece rotor assembly. The drilled pattern on the rotor faces is a functional choice that helps vent gases and heat away from the pad surface, contributing to more stable braking performance, especially under repeated hard stops. The silver finish on the calipers and the drilled rotors give a clean, performance-oriented look behind your wheels.

When installing this kit, ensure you have the proper tools and follow the manufacturer's instructions carefully. This Big Brake Kit is a significant upgrade for your 928, designed to handle increased braking demands. It's a well-built system aimed at providing improved stopping power and feel for your performance Porsche.
