Just as the title states, I'm finally able to understand what my cars are doing when I'm driving, now I need to figure out what to do to make them drive better. Any websites or apps that can help me learn more about setups?

My go to for all my cars has always been the Hudy set up guide

Works great for all my cars..Both 1/10 and 1/8 scale...2wd to 4wd

The Hudy guide is great , I use it as well. I also thought this was a good read too....

Thanks for the links and info guys.

Team Associated also has an application on the Android market that you can install and have handy at the track It's called "R/C Cheat Sheets"

Practice

All great info guys. The one area I really want to understand is roll center. Esp with different shim lengths on hub vs inside

I will also put in my suggestion to review anything that the Hudy guide can offer you as that seems to be the most comprehensive guide out there.

IMO the off road version of it lacks proper method to explain it simply and cleanly. The on road is a bit better but it's tailored more to on road chassis designs.
Nothing beats proper practice. If you want to try different camber link angles and lengths then do so whenever you have time. Usually a 3 minute drive is enough to know how much better or worse a change is.

With out a lot of detail I made a cheat sheet to understand the effects of each adjustment.

Thats a cool little sheet...what does the X-1... X-2 mean?

Sorry when I did this it was with a TLR 22 1.0. So the default was the ball on the spindle side. But now the 22 2.0 has 2 adjustments holes. But the theory still applies.

Front 22 2.0 camber adjustments holes would be 1-2 (inside) and A-B (outside)

Just experiment with it. I'm sure your track has a day dedicated to just practice. Show up and change one thing as a time and run it for 10 minutes or so and document how the car handled. I'm not quite good enough to notice every change but some changes I can tell.

I agree. One change at time makes it easy to see what effect it has.

The stock setup is usually a good starting point also.

Pretty good thread on Roll Center:
