@.rIKmAN: Yes :), the first tip is to me patient. Car physics takes lots of efford, really hard thinking, headbanging, and so on.
The first thing that is important is that you have the basic rolling, and turning correct before you go on with skidding, and ways to calculate the sideway force. The backwheels always points against the wheel infront (ie, left backwheel always points against left frontwheel). Just a hint on basic rolling to get the wheels properly positioned. When everything looks correct at that stage (which is important, otherwize you can't build more on top of it, like skidding).
I talked to a guy I know about the car physics, and he said that the "Physics of Racing" serie is slightly incorrect according to new knowledge, and that the formulas at those pages are very bad explained (which is true), however, the PhOR serie helped me a lot with understanding how it all works.
When you got basic rolling to work, you can start with skidding. It's quite easy to know when it will start to skid, as most (standard) tires by today can handle .8 - 1G on asphalt. 1G on earth = ~9.8 m/s, so just remember that if any force pushing the car anywhere (backwards on accelleration, forward on breaking, or sideway when turning) is higher than 9.8 m/s, then the tires skid (the slowdown rate is the friction between the tires and the road). Then even when it skids, continue to calculate the forces, as the car hooks bak to normal rolling state when the force pushing the car falls back below about 1G (which happens as the car slows down due to friction). When you got it all work on asphalt, then it's very easy to add other friction values for wet asphalt, snow, ice, grass and similar.
I really can't explain everything here, but I hope this helps you a bit into the right direction. Remember, on top of this, a LOT of tweaking and headbanging is needed to get it correct. Good luck ;)!
