Here are set-up wheels for your touring cars running foam tires. These have 5 sides on them for 5 different sizes of foam tires. We all know how suspension settings change as foam tires wear. These set-up wheels give you the ability to set your suspension settings for tire sizes ranging from 58mm down to 56mm in .5mm increments. They are made from aluminum with the edges beveled and the tire sizes engraved after anodizing. The ones in the pics are done in black and match the Hudy set-up system. These could be anodized in other colors as well.
