RE: speed limiter

[Tim Irwin <timi@Interlinq.com>]

If the springs are changed, or your airbox has been modified, that will put
you into SCCA Street Prepared, which looks like a pretty tough category. You
might also check out the "Street Touring" class.

See http://www.moutons.org/sccasolo/ for a good listing of car classes,
modifications allowed, etc.

Interesting.... and good point.  I guess it depends on how strict the
officials are.

 I was curious to know as I'm considering getting into Autocross next
summer myself.  My car came with suspension and air box mod'd which would
still let me compete in stock or near stock category.
