Hub Centric Ring

A hub centering ring for aftermarket alloy wheels for your car. Usually aftermarket wheels have a large center bore so that they are applicable on many makes of car with the same wheel stud pattern. It is advisable to locate these wheels with a plastic spacer ring such as this one.

You need to adjust the inner and outer diameter of the ring for your fitment. The default parameters are for an OZ (CB 75 mm) wheel on a Ford hub (63.4 mm).

I printed mine in PLA, even on a race car it seems to work. It softens when the brakes heat up, but that does not seem to be a problem. The ring serves its purpose while you tighten the lug nuts, afterwards the friction keeps the wheel in place.
