The Brembo front GTS big brake kit for 2015–2021 Volkswagen GTI upgrades the front brakes with six-piston cast calipers and two-piece 355x32mm drilled rotors in black. Offered as a complete front axle replacement, the kit increases pad area and rotor mass to deliver improved stopping power and greater resistance to fade under repeated heavy braking, while preserving a direct-fit approach for listed GTI models.
