Various rear suspension setups, How do they work...
 

Last time I was under the RX-7... Which was a LONG time ago, I remember looking at the Watts linkage and thinking "OH! So that's what it does..." as I visualized how the levers and shit would move if the car were bumping up and down, or being pulled down on one side in a turn...

Does anyone have pics of a Panahrd bar or 3 link setup as so I can do the same? I wanna see how this all works, cause knowing is half the battle.

There is a book, "How to Make A Car Handle" by Fred Puhn that is a good book covering most common suspension designs. Has good illustrations and is written so the average person can comprehend it. I recommend it highly.

is that the $75 book that everyone says is bible like? if so I'd like to get one, does amazon or some similar site sell it?

Nope, the $75 bible is Jim Susko's book that is all about setting up 1st gens, AFAIK.
