Wilwood 140-11269 AERO6 W6A Front Big Brake Hat Kit 14.25in Rotors

The Wilwood 140-11269 AERO6 W6A Front Hat Kit is a complete, bolt-on front big brake upgrade engineered for high-demand street, track, show, and heavy-duty towing applications. Built around Wilwood's forged AERO6 six-piston caliper, this kit delivers massive braking capacity paired with large-diameter rotors to handle the demands of heavy vehicles and extreme-duty use.

The AERO6 caliper features a radial mount design with three staggered piston bores — 1.62 in., 1.12 in., and 1.12 in. — providing a total piston area of 4.04 in² for exceptional clamping force and consistent, fade-resistant pedal feel. Calipers are available in a durable powdercoat finish and accept Wilwood's BP-20 compound brake pads (pad plate #6617) with 11.1 in² of pad area.

The 14.25-inch GT curved-vane rotor features directional staggered vanes (72-vane count) for maximum airflow and cooling under sustained high-heat conditions. Rotors are dynamically balanced and finished in black electro coat for corrosion resistance. Rotor width is 1.25 inches.
