Brembo 96-05 550/575 (Excl. GTC) Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-1-Black

The 380x28mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its ability to handle heat and provide consistent stopping power. This kit is specifically for the rear of 1996-2005 BMW 550i and 575 models, excluding the GTC variant, and is designed to significantly improve your braking performance. The four-piston calipers are a substantial upgrade over stock, offering more clamping force and better heat dissipation, which is crucial for maintaining brake effectiveness during spirited driving or heavy braking situations.

Brembo's GT Big Brake Kits are well-known for their robust construction and performance focus. The calipers themselves are cast aluminum, keeping unsprung weight down while providing a solid foundation for the pistons. The rotors are slotted, which helps to vent gases and dust away from the pad surface, ensuring a cleaner contact patch and more reliable braking, especially under demanding conditions. This two-piece rotor design also helps manage heat expansion and can make replacement easier down the line.

When installing a kit of this caliber, it's important to ensure all components are properly fitted according to Brembo's instructions. This kit includes the calipers, rotors, and necessary hardware to complete the rear brake upgrade. While this kit is designed as a direct replacement for the specified models, it's always a good idea to consult the manufacturer's installation guide for any specific tool requirements or torque specifications to ensure optimal performance and safety.
