18x10s... Who Has These?

The pages I've been looking at for getting some 18 x 10 Roush wheels say they won't fit the 94-95 stangs... or w/ an IRS... Does anyone have 18x10s on your car? I'm curious if it's just a clearance issue w/ the exhaust, or something more serious... any feedback is always great... (also, does anyone know where to get some Silver roush wheels? they're all chrome now... and I'm not that "bling"-in'... )
