I am leaving for the American Iron national race at Mid-Ohio on thurs. morning. I have sitting in my garage a new set of tubular race control arms from Griggs and a coil over kit. Should I rush and put the stuff in or go with my car as is?

I figure I am at a disadvantage to these guys because I built my car for A/sedan which req. stock k-frame and control arms. All the AI guys are allowed to run the tubular stuff and most do. I am hesitant though cause I know how my car is now and dont want to take a chance by rushing to get the stuff in then wondering how it will handle.
