far from being an expert, but i've been playing around with mine. Sounds like the front of your bars are lower than the backs. If you level them out, you will likely find it will squat less. These things are really sensitive to change. Mine were originally opposite to yours (higher in the front) and it would hook up like crazy, zero squat, but the handling was scary, darting left and right, especially gas on/gas off.

Basically, when the bars are higher in the front, when one side drops (due to torque or cornering), the lower bars on the side that is dropping effectively lengthen, (and the other effectively shortens) causing rear over-steer.

I would assume with your bars higher in the front, you have the opposite: rear under steer under cornering/gas on/gas off situations.

Look forward to others commenting! Does anyone have sway bars set up with their 4 link? Can you comment on how that changed handling?
