I like the Idea of going to the LeMahn style pit stop someone above suggested...2 guys work together to change all 4 tires...the pair does all 4. One runs the gun, the other swaps out the wheels. Honestly these sub 4 second pit stops are a joke anyhow...In theory this would cut team cost a ton if they didn't need 20 guys around the car in the pit...I realize most of these guys have other jobs on the car during the weekend, but its something to think about.
