The Brembo GT big brake kit for 2004–2010 A8 (D3) front applications combines 8-piston cast calipers with 380×34 mm two-piece drilled rotors in silver. As a front upgrade, the cast 8-piston design increases braking control while the drilled, two-piece rotors support venting of gases and improved heat management. Two-piece construction also streamlines replacement of rotor components during maintenance.
