Brembo 12-14 328i MSport Brakes Excl xDrive Rr GT BBK 4Pis Cast 345x28 2pc Rtr Slot Type1-Black

This Brembo GT Big Brake Kit uses a cast aluminum caliper body, a material chosen for its strength and ability to dissipate heat effectively under heavy use. This rear kit is specifically designed for the 2012-2014 BMW 328i MSport models, excluding xDrive variants, and features a 4-piston caliper setup. The kit includes two-piece rotors measuring 345x28mm, which are slotted to help clear dust and gas from the pad surface, promoting more consistent braking performance.

The caliper design incorporates four pistons, allowing for more even pressure distribution across the brake pad and rotor surface. This translates to improved stopping power and better pedal feel, especially during repeated hard braking events. The two-piece rotor construction, with its floating hat design, helps to reduce thermal stress and prevent rotor warping, a common issue with high-performance braking systems. The Type 1 slotting pattern on the rotors is a well-known design that aids in pad cleaning and heat management.

When installing a big brake kit like this, it's important to ensure all components are properly seated and torqued according to Brembo's specifications. This kit is a significant upgrade over the factory braking system and is intended for drivers who demand more from their vehicle's stopping capabilities. While this kit focuses on the rear axle, it's part of Brembo's GT line, known for its comprehensive performance braking solutions.
