You know, it would be so much easier if we could just set our tire pressures, select any old set of springs and dampers, and just drive the car. I suppose we could, but that would definitely not lead to the best handling car. So, what to do - how do we figure out what tire pressures to run, and when to soften or stiffen the springs on our car? Just ask... someone like Jeff Braun, race engineer extraordinaire.
