Product details
The red AERO6/GT combination supplies the Skyline R34 with six-piston front calipers and 72-vane 14-inch discs. BP-20 pads use the AERO6 pad envelope, while the included braided hoses connect the calipers without supplying a replacement master cylinder or hubs. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; it is based in Camarillo, California, and serves motorsport, street-performance and specialized applications.
Fitment & Compatibility
The R34 AERO6 installation applies to the listed 1999–2002 Nissan Skyline front disc assemblies. Retained hubs carry the 14-inch rotor-and-hat assemblies, while the supplied radial brackets locate the AERO6 calipers. Confirm the hat register and stud fit before checking wheel spoke clearance; do not select solely by wheel diameter. The included braided flexlines must remain free of contact and tension throughout wheel movement. Installation also requires the dust-shield trimming and caliper-centering checks specified in the linked guide. Nominal minimum wheel diameter: 18 in; 457.2 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
