Features

Note in regards to wheels and tyres.

Unless otherwise stated, wheels and tyres are supplied individually. They are not typically listed as a full set since most vehicles run different widths and offsets front to rear. Please carefully check your PCD, width and offset (ET) when choosing wheels or wheel and tyre packages. If you need more information or clarification, contact StreetFX customer support prior to ordering.
