Description
On BMW 2012–2014 328i MSport Brakes Excl xDrive, repeated speed reduction can quickly become a thermal-management problem. This Brembo rear solution is designed for drivers addressing that limitation at the system level.
Brake-system layout
Brembo’s GT line is aimed at enthusiasts who want a substantial step beyond the factory braking system without giving up everyday usability.
- Axle: Rear
- Brembo family: GT
- Catalog specification: 4-Piston Cast; 345x28mm 2-Piece
Why this setup makes sense
Because this is a performance-oriented chassis where improved heat capacity, pedal consistency, and repeatable braking are valuable during demanding street or track driving, brake performance becomes increasingly dependent on heat management and repeatability as the car is driven harder. This package is intended to support that progression.
Best suited for
Best suited to enthusiastic street cars, canyon use, autocross, and HPDE builds that need more repeatable braking without moving to a race-only setup. As a rear kit, it is especially useful when the goal is to complement a front brake upgrade and preserve balanced brake behavior across the chassis.
Configuration options
- Rotor Style: Type 3 Slotted, Type 1 Slotted, Drilled
- Caliper Finish: Yellow, Silver, Red, Black
Where both drilled and slotted versions are offered, the rotor selection changes the friction-ring treatment while retaining the application-specific package. Choose the version that best matches your intended duty cycle and preferred setup.
