Brembo 06 330i Excl xDrive Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Drilled-Red

If you're looking to significantly upgrade the stopping power on your 2006 BMW 330i (excluding xDrive models), this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to replace your factory rear brake components with a much more robust setup, giving you improved performance when you need it most, especially during spirited driving or track use. It features a substantial 345x28mm two-piece rotor and a powerful four-piston caliper, engineered to handle more heat and provide more consistent braking force.

The heart of this kit is Brembo's renowned four-piston GT caliper, cast from high-strength aluminum for a good balance of rigidity and light weight. These calipers are paired with a two-piece rotor assembly, where the vented 345x28mm iron friction ring is mounted to an aluminum hat. This design helps to reduce unsprung weight and allows for better thermal management, as the hat can dissipate heat more effectively than a solid one-piece rotor. The rotors themselves are drilled, which helps to keep them cooler and can also aid in clearing dust and gas away from the pad surface, contributing to more reliable braking performance under demanding conditions. The red finish on the calipers adds a distinct visual upgrade to your vehicle's rear end.

This kit includes everything needed to install the Brembo GT Big Brake Kit on the rear of your 330i, such as the calipers, rotors, hats, and necessary mounting hardware. While this is a comprehensive kit, it's always a good idea to consult the manufacturer's installation guide for specific details regarding brake fluid requirements and any other recommended procedures to ensure optimal performance and longevity of your new braking system.
