At the risk of showing my age this is what we did. We moved one side forward 1/2 inch. One side back 1/2 inch. This was to increase rollout. We didn't change air pressure in the front tires. AHRA allowed one inch stagger in wheel base. There were no reaction times back then. Also we could roll in a little deeper without fear of red lighting. Deeper stage, even a few inches would take some et off.
