ADVAN Racing RG-4 18x8.5 +37 5x114.3 Wheel - Copper Bronze - YA48H37ECB

The ADVAN Racing RG-4 YA48H37ECB is a 18x8.5 performance wheel configured with a +37 offset and 5x114.3 bolt pattern. This version uses a 73mm hub bore, 73mm center-cap size, M14 lug-hole specification, and the GTR design configuration, finished in Racing Copper Bronze. The RG-4 series is offered in multiple diameters, widths, offsets, lug-hole specifications, hub bores, and design configurations, so the complete specification set must be matched to the intended vehicle. Confirm brake-caliper clearance, suspension clearance, fender clearance, tire sizing, hub compatibility, and wheel-hardware requirements before ordering rather than relying on wheel diameter or bolt pattern alone.
