I don't know, I've never seen one for these cars but if its a skinnier bolt I'd rather have the strut slot instead. If a guy wanted to get fancy about it, he could weld up the side of the hole opposite the enlarged side and then neatly grind or drill the hole in the altered position so theres no play possible. Thats truly overkill though, because the slot creates no issues and costs zero. Perhaps regulations dictate that camber bolts be used in some areas, or at least suggested. I have no idea why camber bolts are even offered for these!
