Would anybody know if it is possible to mount the 20" wheels found on Ifiniti's FX45 sport ute. The bolt pattern for these infinti is 5x114.3 or 5x4.5 in inches. There are some moderately priced knockoffs for sale. They have the option of chosing a center bore of 65 or 72. I don't know what the center bore on the 300 is. Any help or positive ideas is greatly appreciated.
