Description

Built around the needs of Audi 2008–2017 S5 / 2009–2016 S4, this Brembo rear system gives the chassis a more serious foundation for repeated hard braking.

What this package is

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; 380x28mm 2-Piece

Recommended driver profile

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.

Why it suits this chassis

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, 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.
