The Wheel Fit allows for accurate measurement of correct backspacing or offset and wheel diameter by mounting a tire in an adjustable position on the car. This mock up tool can be mounted to the hub and clearances checked, all while turning the steering. Never buy the wrong wheels or compromise on generic fitment again. These are a must for custom offset wheel orders.
The Wheel Fit Professional 45 will fit most all 4- and 5-lug vehicles including bolt circles ranging from 4-100mm up to 4-130mm and 5-100mm up to 5-5. This kit will extend from 14" – 20" in tire bead diameter. It will also extend from 6.5" – 16" in width. Backside setting is completely adjustable within the constraints of the tool. A ruler mark is engraved on the side of the tool to indicate backside setting and width measurements.
