'94 to '04 GT or Cobra will work... There are several different styles and sizes (17" and 18"; 8", 9" and 10"). I think that the 17s from lower models of some generations were narrower and I doubt I'd like the feel of a 255 on a 7" or even 8" rim; Especially on a track for hours upon hours.
There's a huge thread on this over on SM. I'll try to find it and post a link for you.
