then why do they put so much caster in Sprint karts? Answer; because if you don't get that inside rear tire off the ground, the kart will push.
Why do we have stagger? Answer; so that both rear tires can be rolling around the turn, versus having one sliding and one rolling. The closer both rear tires come to the same circumference, (and the smaller the radius of the turn the more this is true) the more the kart will tend to push. Of course this is only true if the LR is on the ground. And, if it's on the ground, and the stagger is correct for the turn, you have more side bite. A sliding tire has less traction than a rolling tire.
