I have seen the Evos run AS here in houston and they used to do rather well on their street tires. Nobody really tried to do much more.
The STI has beter TQ but a well setup Evo in AS should do well nationally. I am thinking at least as competitive as the Boxster S I'm running now......so say a top 5 car.
As for tires....easily 245 Hoosiers and maybe the 275s would clear the fenders. If so I'd look into them :)
And maybe some trick shocks.....Motons or 2812s or ASTs or Penskes.
