Description

For owners of Audi 2004–2008 S4 / 2006–2008 A4 building beyond the stock braking envelope, this Brembo rear kit offers a purpose-built route to greater thermal headroom and a more performance-focused pedal experience.

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.

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.

Core specification

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

Variant choices

  • Rotor Style: Type 3 Slotted, Type 1 Slotted, Drilled
  • Caliper Finish: 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.

Brembo’s supplied fitment data for the SKUs grouped here includes select 2006–2008 Audi A4, select 2006–2008 Audi A4 Quattro and select 2004–2008 Audi S4. The storefront title is centered on Audi 2004–2008 S4 / 2006–2008 A4; if your vehicle falls elsewhere in the broader fitment list, verify the exact selected SKU and submodel before ordering.
