They are stockers pick them up anywhere cheap. car-part.com
I think our old 99' 9-3 had 15" ones on it too - I scrapped them for $40 (they were all bent)My 98 900s had a 15inch version of this wheel
To be honset, I have no idea. I think someone just started throwing it around and it just sort of stuck. It seems most people know exactly which wheel you're referring to when you call them that too.SO please tell me, why are they called Klingons? Never could figure that one out...
