Or soften the sway bar.
Or stiffen the front (take away steering).
Or lower the roll center.
Or change tires.
Or move the shocks more inboard (more leverage ratio from the arm makes the spring effectively softer).
Or a bunch of other things.

Be mindful when people say things like "more traction" they are usually speaking of the chassis in a steady state corner, like on a skid pad. Softer springs make the car a little slower on input from steering and throttle.

When I ran my truck with blues on it, it would push midcorner and then snap around at corner exit, jumped poorly, and was kind of lazy.

Out of curiosity, how many shims do you have under the inner ball stud in the rear?
