Wheel Adapters from fast wheel accessories ship fast and free and are made out of the highest quality material.  

People install wheel adapters when they want to change the bolt hole spacing for their rims. For example, if you have a 5-lug wheel with a 4.5-inch bolt hole pattern, you can only use wheels that fit those measurements. If you locate wheels that you want to install that do not fit that pattern, you must install a wheel adaptor with the wheel spacing for the wheels you want to install.
