So you are upset, because your cage you bought from Jegs, would not pass the written spec. And that is somehow NHRAs fault and not Jegs................wow. Tubing is always measured in the bend, because, yes it stretches....but....if jegs had used something other than the cheapest crap they could get, it may have passed. The spec is .120 wall mild steel and can be no thinner, ANYWHERE. That is why most kits, made with cheaper ERW tubing are actually made from .134 wall. To make sure they pass the spec. The fact that it passed before, only means that inspector did not happen to measure it in a thin spot.
