If you want the tightest handling you'll want both front and back shocks as stiff as possible and even stiffer springs in the rear or a stiffer rear sway bar.

Ideally you'd make the front sway bar thicker, the rear sway bar even thicker than that, all springs and all shocks stiffer, and tie bars all around to stiffen the chassis.

I'm going to go put Viagra decals on my tie bars, now.
