Brembo 05-08 7-Series (After 3/5 Prod) Rear GT BBK 4 Pist Cast 345x28 2pc Rotor Slotted TY3L - Black

This Brembo GT Big Brake Kit for the rear of your 2005-2008 BMW 7-Series (produced after March 5th) includes everything you need to significantly upgrade your braking performance. You get a pair of black 4-piston GT calipers, two-piece 345x28mm slotted rotors, and all the necessary hardware for installation. This kit is designed to replace your factory rear brake setup with a much more robust system, offering improved stopping power and heat management for a more confident driving experience.

The calipers are cast from aluminum for a good balance of strength and weight, and feature a 4-piston design. This means more clamping force is applied to the rotor surface compared to a typical 1 or 2-piston caliper, leading to shorter stopping distances. The two-piece rotor construction, with a 345mm diameter and 28mm thickness, helps dissipate heat more effectively than a single-piece rotor. The slots machined into the rotor surface help to vent gases and dust away from the pad, maintaining consistent braking performance even under heavy use. This is particularly beneficial for heavier vehicles like the 7-Series, which can put a lot of stress on the brakes.

Installing a big brake kit like this is a significant upgrade, and it's important to ensure it's done correctly. While this kit is designed as a direct replacement for the factory components, always refer to the manufacturer's installation instructions for specific details and torque specifications. You'll likely notice a substantial difference in pedal feel and braking responsiveness, especially during spirited driving or when carrying a load.
