The Brembo GT big brake kit for 2014–2020 Audi A3 front applications pairs four-piston calipers with 345 x 30 mm one-piece cast rotors. This front BBK uses slotted Type3 rotors and a black finish, supplied as a vehicle-specific upgrade to replace factory front braking components. The kit matches the A3 application with larger-caliper and rotor hardware for direct fitment.
