Brembo 06 330i Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Black HA

This is the Brembo Rear GTS Big Brake Kit for your 2006 BMW 330i. It's a complete rear brake upgrade designed to give you more stopping power and better heat management. If you're pushing your 330i hard, whether on the track or just enjoying spirited driving, the factory brakes can sometimes struggle to keep up, leading to fade. This kit addresses that by replacing your stock rear setup with a much more robust system.

At the heart of this kit are the Brembo 4-piston calipers, which offer increased clamping force over the factory calipers. These are paired with a 345x28mm two-piece rotor assembly. The rotors are drilled, which helps to vent gases and heat away from the braking surface, maintaining consistent performance even under heavy use. The two-piece design allows for better thermal management as the hat can expand and contract independently of the friction ring. The black HA finish on the caliper housing is a nice touch for aesthetics, and the overall construction is well-built, as you'd expect from Brembo.

This kit includes everything you need to get the rear brakes upgraded, including the calipers, rotors, and mounting hardware. It's a significant upgrade for anyone looking to improve their car's braking performance. Remember to consult the manufacturer's installation instructions for specific details on mounting and any required brake fluid changes.
