This is a set of "factory" FORD Style wheels for the FMS Magnum truck. These increase the track by 2mm per side, fit the factory tires, and just replace the wheel face. Please see the video below prior to purchasing as the retaining flanges on the hubcaps are fragile. The screw bosses on the back of the hubcap are also weak spots so even a bit of heat from a hair dryer could prevent cracking.
These have only been printed with a Polyjet and SLA Printer. It is likely an FDM will not work.
