The Brembo front GT big brake kit for 2004–2008 Audi S4 (B6/B7) is a front GT package featuring 6‑piston cast calipers with two‑piece 355×32 mm drilled rotors in black. Built for direct‑fit front installation on B6/B7 S4 models, the kit increases rotor diameter and piston count to improve braking modulation and heat handling during aggressive driving, and uses two‑piece rotors for easier serviceability.
