The Brembo big brake kit for 2004–2008 Audi S4 (B6/B7) front replaces front braking with a GTR BBK featuring a 6-piston billet caliper and two-piece 365x34 mm slotted Type 1 rotors in a nickel-plated finish. It improves thermal capacity and braking modulation for dynamic driving. The slotted rotor design aids cooling and debris clearance while matching the front-axle fitment specified.
