Sorry I'm a noob at autox classing. The SCCA solo pdf file is dizzying with the sheer amount of info on there. so i ended up reading http://noraracing.net/new-to-autocross/car-classing
so why is it better in stx than str?
Yeah, Vinh, since I planned on going ST from the get go I went with a wider than stock wheel, so that bumps me straight to ST. And yes, there's a lot of info in the SCCA rulebook. You should check out the rulebook for a wheel-to-wheel series sometime. I'm trying to build a Chump Car right now and I spend more time reading rules than anything else. And that rulebook is thin compared to the racing series's not tailored to $500 crapcans!

As far as STR vs STX, go to the sections showing which cars are legal in which classes, then look at the nationals results from last year. For STX it's Civic Si's, some e30 and e36 BMWs, and some RX-8's for the most part. STR is mostly populated by S2000's. We can have a lot of fun in STR, but we probably won't ever be competitive with the S2000s directly. They have more power, torque, and displacement. The RX8 is a much better benchmark if you want to compare power vs weight. I had a hotshoe STX RX8 driver drive my car at a Cenla autocross school a few weeks ago and he made the comment that it felt like his RX8. Obviously not a quantifiable comparison, but it gives you a good idea of where the car belongs. If it gets classed in STR it simply won't ever win a national title. In STX it has a pretty good chance.
