Looking through that website posted above, consider theory vs reality. You can spend hours memorizing everything on that website, but once you get to the track, you will have so much going through your head that it makes it easy to get lost. I think it's far more beneficial to spend time at the track focusing on link positions than spending the same amount of time researching roll centers online. It's like reading theory in a textbook vs actually doing it. The basic info in the telenet, JQ, and Hudy guides are good, but the only way to truly understand is to do it yourself.

Another way to learn quickly is while marshaling or watching experts race, focus on each cars handling traits. Take note of how much the car rolls, it's steering, when it breaks traction and what causes it, and how aggressive the driver is.
