This is a three-piece forged aluminum racing wheel set, compatible with vehicles requiring a 5x112 bolt pattern.Available in diameters from 18 inches to 26 inches, these wheels feature a gray deep dish finish.The design accommodates an offset of 25mm or 40mm and is intended for fitment on models including the R8.Wheel construction follows standard three-piece forged aluminum methodology, with the inner barrel and outer lip capable of being finished in different colors upon customization.Customization requires specification of vehicle model and year, front and rear wheel dimensions (e.g., width and rim diameter), offset (ET), pitch circle diameter (PCD), center bore (CB), desired style, and color preferences.Measurements for lip and barrel width are taken from bead seat to bead seat, not overall outer.Bore size is measured as the diameter of the center hub.
