While I have been a door car guy all my racing career and have no desire to go to a dragster, I have a couple of friends that run them and love it, both started out with door cars, one being a tube chassis chevelle,,I remember him saying that the fit of the chassis to your body is crutial and that comfort is paramount after he bought a rolling chassis that didn't fit him as well as he liked and spent the next winter having it modified to fit him, plus went from a hard tail to a springer w/ a single monoshock,,so he added a lot of time and money that could of been better if he would of gotten the right chassis the first time, but he now has a really nice setup that he is very proud of and happy with.
