Corner-weight measurements were taken before our ’02 Mustang GT was tested at the dragstrip in street/road-race and street/’strip trim. Adjusting the corner weights is done by placing the car on four perfectly level scales, then adjusting the car’s height at each corner. To add weight at a given corner, the spring at that corner is raised and its opposing spring lowered (by adjusting spring perches). The scales showed us that control arms, shocks, springs, struts, wheels, and tires designed for hugging curves are much heavier than their drag-race counterparts. Our ’Stang’s poundage (with driver) went from 3,827 at Fontana to 3,723 when the lighter wheels and tires were installed for testing in Las Vegas.
