My personal definition would be the removal of excess material that does not affect the shape or contour lines of the vehicle. Does anyone have any other input on this? I got into an elevated "discussion" with an offical about it (mainly about gutting the A-pillars and roof) and just want to get some opinions if possible.

My defination of "hulling" would be the same as the tech man at my track to avoid any DQ type problems. LOL

Seriously, though, it's going to vary by track so anybody else's definition of it shouldn't really matter. Our rules specifically state what parts of the car may be hulled. With regards to those parts, I consider it to be removing the inner layers of metal so that only the skin remains and looks the same as stock from the outside.

I rolled my car two years ago, and not knowing the first thing about hanging a body, I had no clue how to go about replacing the top, and everything else. Some of the inner ribbing was bent, so I felt I should cut back as much as possible to ease installation of the new skin. I heard people rumbling about the way my car was on the inside, complaining about it being lighter. 65 lbs is what I pulled out of it, and I actually wished I had been able to keep the weight there instead. If rules are seperate like association rules, and track rules, then I'd try to get the best definition possible. The best place to remove weight is from the driver, and forward. What made you have to remove the A-pillar?

I took a really hard hit right behind the left front wheel and got the A-pillar. It also gave me more room to move the body back a couple inches to get closer to the cage.

Here are the rules for the body: (I have a metric)

2- HULLING- OF BODY IS PERMITTED.SUB-FRAMES/UNI-BODY CHASSIS MAY BE TIED TOGETHER FOR SAFETY. MUST BE FULL CAGE CONSTRUCTED OF AT LEAST 1.5" STEEL TUBING.YOU MAY USE PLASTIC NOSE AND TAIL PIECES.
3- FENDER WELLS MAY BE REMOVED.
4- FRONT INNER FENDERS MAY BE REMOVED.

Your rules leave it wide open to interpretation. What weight rules do you have? When I built my car three years ago, we bought a deluxe kit from Stock Car Products, and installed it. We had no knowledge of weight percentages, cross weight, etc. If I could afford it, I'd build a much lighter, and just as strong version of what I have now, and it would allow me to move the weight further back. If the rules allow it, then cut away, but be warned......lighter isn't always better, especially if your laying down a lot of bottom end power.

Hutch, I agree with you. From reading the rules I say gut everything!!! A lighter car is ALWAYS better given the proper weight%

I may have missed it, but can you add lead ballast to your car? If you can then they are right, gut the entire thing. If you can not then take in certain areas to achieve the percentages you want. We run a camaro and the only thing left of the stock interior metal are the rockers floorpan from the driver forward and part of the firewall.
