SCCA is considering adding Pro Touring classes.

Hmmm, that is interesting. Since Lincoln, NE is so close to here, a lot of our guys travel to the National events there and set their cars up to run in classes that they can compete in there. There are some of them that are trying the new road tire classes this year...talk about a PAXing nightmare to try to figure out. The PAX makes sense when handicapping stock cars, but above and beyond the stock classes it doesn't make much sense to me either.

I'm not that familiar with ESP, how much suspension modification can be done to an ESP car.

Basically it sounds like you can either use tires, or extensive suspension mods, or both to make your car handle better and be classed accordingly.
