How Do I Tune Suspension For 4WD and RWD?

[CarCzar]

When I started drag racing, I neglected my suspension. I thought it didn't matter. I got whaled on.

Now I have been making attempts at tuning my suspension, but to no avail. My cars can keep up, but they are not always winning cars. I am wondering what I am doing wrong. I am not asking for your particular suspension, just general advice.

Here is what I have so far: (Please Show me and the others viewing this what I am doing wrong)

4WD (Audi Le Mans)

Ride Height: -10/-8
Spring Rate: 10.0/7.3
Extension: 8/2
Compression: 2/8
ARB: 4/4
Camber: 0.0/0.0
Toe: 1.00/1.00

RWD:

Ride Height: -10/15
Spring Rate: 16.0/9.0
Extension: 8/2
Compression: 2/8
ARB: 4/4
Camber: 0.0/0.0
Toe: 0.00/1.00

Reverse your spring rate, lower your tow to .75 to .85. Minimize your ARB.

In both drivetrain setups or which one?

Both

So other than the toe and the things that needed to be fixed are the values, too low? too extreme?

Toe needs to be lowered, and swap the values for the rest

for 4WD your rear spring rate should be stiffer than the front to eliminate squat
