Brembo 19+ 330i Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Drilled-Red

Brembo is well-known for their high-performance braking systems, and this Rear GT Big Brake Kit (BBK) is a prime example of their expertise. Designed for the 2019 and newer BMW 330i, this kit replaces your factory rear brakes with a substantial upgrade, focusing on improved stopping power and heat management for spirited driving. It’s a comprehensive package aimed at drivers who demand more from their vehicle’s braking performance.

This kit features robust 4-piston cast aluminum calipers that offer increased clamping force over stock. They work in conjunction with large 380x28mm two-piece rotors. The two-piece design helps reduce unsprung weight and allows for better thermal management, as the rotor can expand and contract more freely. These rotors are drilled, which helps to dissipate heat and gas buildup, contributing to more consistent braking performance, especially under heavy use. The calipers are finished in a striking red, adding a visual performance cue to your vehicle.

When installing a big brake kit like this, it’s important to ensure you have adequate clearance within your wheels for the larger calipers and rotors. The kit includes everything needed to upgrade your rear braking system, providing a significant improvement in both feel and performance. This is a serious upgrade for those looking to enhance their 330i's track or aggressive street driving capabilities.
