Just kidding.

AtomicLabMonkey,

I thought you were right on in the brake thread and I'll say it again here. Right on!

With the WRX, and I'd assume with any AWD strut car, you've got to find a good balance between reducing chassis roll while maintaining tire compliance.

At one point we were running 1,100 lb/in rear springs to get the car to rotate. It did, but it was so stiff that it pretty much made the tire the only moving part of our suspension.

Softening springs will allow so much body roll that you get significant dynamic camber gain. You can see this in almost any photo of a WRX in a corner on an autox track. So you need to control the roll with stiff swaybars.

The setup that has worked the best for us is 750lb/in front springs, 650lb/in rear springs, 26mm x 3mm tubular front swaybar and 26mm x 6mm rear tubular swaybar. And lots of negative camber.
