At Bloomington tire's, wings, brakes, shocks, and engine seals are checked BEFORE each contested event (qualifying-feature) in the line-up/ push chute. Car/Driver total weight is checked post heat and feature. The top 3 usually or selected at random engine's are tech'd post feature for cam lift, valve spring pressure at seat and .500 lift, pistons etc....
If I am the tech inspector at Lawrenceburg it will be done much the same as I do at Bloomington.
