As Ronin says, there are so many variables that suspension setup is a black art.
If your driving surface is smooth and grip levels are high then a stiffer setup will give you less weight transfer, if your surface is rough or low grip then a softer setup will give you more compliance and grip.
Ditto with the kind of corners. At high speed you want the car to roll a little more so it can put downward pressure on the outside tyres to improve grip while having the car break away progressively should you exceed grip levels - too stiff suspension makes the car skatey and when the tires do let go then it will be sudden and big.
By the same token, on a low speed, tight, twisty course you want the suspension stiffer so the initial response improves and on that course you're on your toes anyway.
It will also depend on your driving style. Some people like the car to be as darty as a go-kart regardless of speed, other people like being able to exploit weight transfer to improve grip at certain ends of the vehicle.
If you can give us a description of the kind of roads that you want to set the car up for, then people might be able to point you in the right direction.

Understeer is when you hit the tree with the front wheel.
Oversteer is when you hit it with the back.
Horsepower is how hard you hit the tree...
Torque is how far you drag it...
