You should be absolutely fine with the Y2k wheels. I didn't have rubbing whatsoever, but then again, the CCW's had an offset/backspacing specifically designed for the SN95 chassis. The Y2k wheels fall into that same category anyway since they came on an SN95 chassis'd Mustang. Just for kicks, here is a photo of my car that may help you (btw, I sold the car back in April to "fastmach01").
