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.
