Wilwood Front Brake Conversion for Chevrolet Tri-Five ProSpindle Cars (1955–1957), Red AERO6 and 14-Inch SRP Drilled/Slotted Rotors

AERO6 six-piston front calipers are paired with 14.00-inch rotor rings and replacement aluminum hubs for the Wilwood Tri-Five ProSpindle. Red calipers and 14.00-inch SRP drilled & slotted rotors are the selected configuration. Its thicker rotor specification and AERO pad format distinguish it from the Superlite packages. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized systems, with selection governed by the complete brake installation.

Fitment & Compatibility

Install around Wilwood's 2.00-inch-drop ProSpindles, ordered separately as 831-16660, with customer-supplied original steering arms. The AERO6 conversion has a 0.34-inch per-side outward track change and needs the 18-inch wheel envelope checked against the drawing.

Compare the replacement hub pattern and select the flexible brake hoses before assembly.
