Description
Brembo developed this configuration around BMW 2006–2012 325i / 328i (Excl. xDrive), pairing the correct axle-specific hardware with the braking architecture needed for more demanding use.
Where this kit earns its keep
This application is a performance-oriented chassis where improved heat capacity, pedal consistency, and repeatable braking are valuable during demanding street or track driving. That makes the value of the upgrade less about a single maximum-effort stop and more about maintaining predictable braking response as temperatures rise.
Hardware summary
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
Selectable variants
This parent listing has a single cataloged configuration in the supplied file, so there is no cosmetic or rotor-style selection to make before ordering.
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.
