C'mon caferacerx, just because his terminology was a little off there's no reason to be a internet thug, not everyone grew up web-savvy. Lets not turn this into a pissing contest. Dude's just trying to get some info.
No problem. As others have mentioned, if you're serious about competing then you'll want to get a copy of the rules from the organization you'd like to race with. Nothing worse than finishing a build and finding out you can't compete because of you mods, or that you've got to compete in the unlimited class against old factory racers.
And look up autoXcuda in the members list here, he's got a very well set up car and racing experience. There's quite a few threads on here with more info, try searching autocross, autoX, road racing, etc. There's also info on each one of the mods I posted, looking up info on subframe connectors alone should give you dozens of posts to sort through.
