First track night rodeo! UPDATE

[Jeff Kleiner]

...The best advice he's given me, which I've taken to heart, is that my tires can only do one thing well at any given moment...

The classic "Traction Circle" which I refer to often when instructing. This guy is kind of dry and bumpy with his delivery but gets the point across. You have to also keep in mind that although his example shows a "square" (with equal forces on both axis) it can be a rectangle as well (with more on one axis than the other). The trouble comes when the forces intersect outside the circle!
