I suppose I should have expanded a little more on my above post. These other guys have made some good points.
Ajustability in a race car is what we want, but too much can be a bad thing if you dont know were you are going with it.
So you weigh the corners and find all the bias and center of gravity etc, now what, were do you go from there?
This is were a good chassis guy can help you out.
some advice here would be to get Dave morgans book, at the least. Also good is the one from Jerry Bickle. Print out and read several times the above sticky thread on chassis tuning. These alone will get you in the right direction.
You can get yourself in a lot of trouble changing things on a car without knowing why you are doing it.
