We all 'get it' Rob, but the sport at the local level is a lot different than the National level. The rules were designed for those who are serious about it, entry level motorsports or not. We're not talking about a sport that has been around for 5 years either. This year's 'Nationals Finale' was the 31st consecutive year, and autocross has existed for a lot longer than that. 1100 cars came from around the country in 2003 to Nationals, and 1200 the year prior.
When someone suggests using 'OEM' shocks, spec tires, etc., they really don't understand how hard that is to police. What about cars that the OEM shock doesn't exist anymore? A spec tire would mean that infinite size ranges are created by one tire brand and model... that will never happen. What about cars like the '84-'86 SVO Mustang and Neon ACR's that came with OEM Koni single adjustable shocks?
I'm trying to be rude in saying this, but people new to autocross have no clue how long it's taken the rules to evolve and what is deemed as a 'simple' fix is never quite as simple as you think. Take a look at
www.sccaforums.com. There were a few people pushing for rules like you wanted. Their id's are 'Cole' and 'RSCamaro92', just to name a couple. Run a search on their posts, and take a look at the reactionary posts. It should explain a lot. 'Cole' even sent in a suggested classing called, 'Stock Street Tire', for he felt that there should be a National based class created for street tired cars(like STS and STX). It was shot down by the Solo Events Board the same month it was submitted. Just because you want to compete locally and have fun does not mean someone needs to create a class for you to run divisionally or nationally and be competitive. If you get serious about it, you'll buy the 'right' car for the class, prep it to the letter of the rules, and try you luck nationally. - AB
