This Brembo GT kit upgrades the front brakes with 4-piston, two-piece fixed aluminum calipers finished in gold and 326 x 30 mm one-piece discs with Type 1 slots. The radial mount calipers clamp with opposing pistons, and the larger disc adds swept area and heat capacity over the factory front brakes. Each kit covers one axle and includes pads, brackets and supply lines.
