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

If you're looking to significantly upgrade the stopping power on your 2005-2008 BMW 7-Series, especially those produced after March 2005, this Brembo GTS Big Brake Kit for the rear is a serious consideration. This kit replaces your factory rear braking components with a high-performance setup designed to handle more demanding driving conditions and provide a more confident pedal feel. It's built around a robust 4-piston caliper and a two-piece rotor assembly that work together to dissipate heat effectively and offer improved braking force.

The heart of this kit is the Brembo 4-piston caliper, which offers greater clamping force than a typical 2-piston caliper. Paired with the 345mm x 28mm two-piece rotor, which features a drilled surface for heat management and gas/dust evacuation, you get a well-built system that can stand up to repeated hard braking. The drilled pattern on the rotor helps keep temperatures down, reducing the chance of brake fade during spirited driving or heavy use. The cast iron construction of the caliper is known for its strength and ability to handle the stresses of braking, while the two-piece rotor design allows for better thermal expansion and can make replacement easier down the line.

This Brembo kit is a comprehensive upgrade, aiming to provide a noticeable improvement in braking performance and feel. It's a substantial investment for those who prioritize braking capability and want a system that matches the performance potential of their 7-Series. When installing a kit like this, it's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures, and consider flushing your brake fluid to ensure optimal performance with the new components.
