255s all around is such a proper setup for an S2000. If the wheel is a 9", and has an offset with anything below +40, you're gonna need a full flare, not just a roll and pull.

I was able to get away with a few different 255 square setups on my old S with just a slight pull, along with front camber maxed to -2.5. One setup was a 9 +45 Advan RS with 255 RE11s, and another was a 9.5" +47 CE28 with a 255 A048 (an extremely wide 255).
