The Z06 standard brake upgrade kit for Z51 vehicles features two piece iron slotted rotors, measuring 370mm x 34mm in the front and 365mm x 26mm in the rear with aluminum mono-block six-piston and four-piston fixed calipers, respectively. The front calipers feature vented pistons for improved pad and brake fluid cooling, including pads 39% larger than those found on the stock Z51 vehicle. These calipers offer differentiated piston diameters of 30, 34, and 38mm (leading to trailing) to ensure more even pad pressure for improved pad wear.
NOTE: These brakes will not fit under stock base or Z51 wheels. Requires a minimum 4mm wheel clearance between the outboard face of the caliper and the inner wheel spoke. This application is for off-road use only because the stock Z51 wheels do not fit over the Z06 brakes. Any failures occuring as a result of the non-production wheels selected by the customer would not be covered.
