I do have a question about that link, however. I have been reading STX and STS rules for AutoX rules, but the one you posted has me worried. Such rules as:
Rear spoiler - N
Strut Bar - N
Spoilers and Cosemtic Trim Pieces - N
What if your car comes with these pieces stock? Does this mean your car is automatically pushed up to Street Prepared? Just wondering since I would not mind autoX'ing, but if I get a car stock that already comes with these 'improvements', I don't want to have to SERIOUSLY modify my car to be competitive.
Check out slowSER's link to go in-depth into the rules. As for what you asked, as long as the cosmetic pieces weren't dealer installed, you're good to go. If they were, check out slowSER's link(I can't rememebr off hand).
