Product Details
This Brembo GT Big Brake Kit features 345x28mm two-piece rotors, a substantial upgrade over stock components. The kit is built around robust four-piston calipers designed to clamp down on these larger rotors, offering a significant improvement in stopping power and heat management for your 930 model vehicle from 1978-1989.
The two-piece rotor design, with its floating hat and rotor assembly, helps to reduce stress and thermal distortion under heavy braking conditions. The rotors themselves are slotted with Brembo's Type-1 pattern, which helps to vent gases and heat away from the pad surface, maintaining consistent braking performance even during spirited driving or track use. The calipers are cast aluminum, keeping weight down while providing the rigidity needed for effective braking. The silver finish on the calipers and the rotor hats offers a clean, performance-oriented look behind your wheels.
This kit is a comprehensive solution for enhancing your vehicle's braking system. It includes everything needed to upgrade the rear brakes to a high-performance standard, offering a noticeable difference in pedal feel and fade resistance. For installation, it's recommended to consult the manufacturer's specific instructions to ensure proper fitment and function.
