Bolt pattern is the same as the SN95. Unfortunately the 99 Cobra wheels will not fit, and I am unsure about the 98's. I saw a picture of an SVO with a set of 97 Cobra wheels...looked HAWT! So I'm thinking either the polished 97 Cobra wheels, or those tri-spoke 17inch GT wheels powdercoated black with a polished lip (i.e. '93 Cobra R lookalikes).
But I'll be rolling around on the SVO stockers for a while. When she needs tires I'll look into some 17's.
