Description
Brembo developed this configuration around BMW 2012–2014 328i MSport Brakes Excl xDrive, pairing the correct axle-specific hardware with the braking architecture needed for more demanding use.
Kit overview
Brembo GT-R systems sit above the conventional GT range, emphasizing lighter, higher-spec hardware and stronger track-focused capability for drivers who repeatedly work the brakes hard.
- Axle: Rear
- Brembo family: GT-R
- Catalog specification: 4-Piston; 345x28mm 2-Piece
Chassis-specific benefit
For a performance-oriented chassis where improved heat capacity, pedal consistency, and repeatable braking are valuable during demanding street or track driving, consistent pedal behavior and thermal reserve can matter as much as outright stopping distance. This kit is positioned around those demands rather than simple cosmetic upgrading.
Where it fits best
Best suited to advanced HPDE, time-attack, and heavily modified street/track cars where repeated high-speed braking and lower component mass are meaningful priorities. 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.
Selectable variants
- Rotor Style: Type 3 Slotted, Type 1 Slotted, Drilled
- Caliper Finish: Nickel
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.
