Not to sound like too much of a patronising c*** but instead of asking questions why not go do some research, there is masses of material on here, svrider, BARF, WERA racing forums, TWF racing etc. What it sounds like you have is idle curiosity which should be sated by reading and learning then possibly doing, you'll learn a hell of a lot more random sh*t which will come in handy too.
