I bet they will never approve that one. these after market chevelle clips are weak. not saying that they should with stand a huge crash but i was hit with a tire in the left front twisted the left horn down as if turning your arm.

The Howe clip HAS been approved at Some Michigan tracks that I know of..They are all looking to the future of not having any good old clips VS the cheap kits that can be tweaked any which way you want..They are all serial numbered as well. I also believe that Port City now offers a fab clip for mods as well.
Technical inspection is costly, time consuming, overburdening.
Stock clips or not, without the ability to properly check race cars at the track after the race cheaply and easily any rules written anywhere for any class relies heavily on the honest racer factor. Money and pretige are the main factors on why we do this which opens the door to fudging the rules so whether aftermarket or tube clips the issue remains or even possibly gets worse.
GM didn't make the clips meant for race cars so some tolerance is already built in but I think asking a racer to leave it alone aside from removal of minor stuff will net a fairer result than asking the racer to build from scratch and build in all the compromises themselves. I don't feel like either is a good solution but I don't have a better one either aside from having one or two approved manufactures put these things together but that's going to raise the costs that are already having a negative effect on racing at that same time.
The crossmember has been narrowed up for radiator clearance, and the hump outside of the spring bucket has been flattened out for shock clearance.
