I was surprised each time i have re-certed my car how the NHRA inspector go/no go gages each bar, sonic checks each bar even the under car bars. I was a little nervous when he stood up aftwer inspecting underneath & asked what chassis shop built this car? I said "my buddies & I did, it's home built" & he said "it is one bad ass m.f'er & I am a Chevy guy". Made me feel pretty good for a guy that inspects thousands of cars a year to compliment mine.
