Fitment & Compatibility
For the 1995–1998 Nissan Skyline R33 front disc spindle and hub. This is the 12.88-inch Superlite arrangement, so use its own wheel-clearance diagram when checking the installed wheels. Center each hat on the hub with the specified register hardware; modified studs or hubs may require machining. The stainless braided flexlines are included and must be routed clear of the wheel throughout steering and suspension movement. Follow the installation drawing for radial-bracket shims and dust-shield trimming before the final caliper alignment check. Nominal minimum wheel diameter: 17 in; 431.8 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
