The Brembo GT front big brake kit for 2000–2002 Audi S4 installs four-piston cast calipers with two-piece 355x32 slotted Type1 red rotors as a direct front upgrade. This kit replaces factory components with larger rotors and multi-piston calipers to improve braking feel and thermal management for more demanding driving without altering original mounting points.
