Description
For BMW 2008–2013 135i, this rear-axle Brembo setup is aimed at drivers who want a braking system that better matches the chassis once pace, tire grip, or track use increases.
Brake-system layout
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
Who benefits most
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.
What it changes for the car
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.
How to spec the kit
- Rotor Style: Type 3 Slotted, Type 1 Slotted
- Caliper Finish: Nickel
The available slotted configuration is oriented toward drivers who value an active friction surface during repeated performance use.
