Running wheel spacers? You need longer bolts. the factory ones won't have enough thread engagement and that's a safety issue, not a cosmetic one. Apex lug bolts in M14x1.25 are the correct thread for your BMW. Pick the length that matches your spacer thickness, or go with standard 28mm if you're just replacing worn or corroded factory bolts. Silver finish. Sold individually. select the quantity your application requires.
