Trust me, you'll change your mind on the decarbons once you put the bilsteins on. The stock Fbody shocks are that bad. Sam will set you up correctly. I dealt with him on my Formula back when I could afford to autox. He knows how to make a 4th gen move through the corners. Check out
www.frrax.com for more on the 3rd/4th gens and making them handle.
Good luck with it all.
