In my quest for better handling, whats next?

I think you’ve got most of the big stuff already. Your torsion bars and rear springs are good, you’ve got a decent alignment and the control arms taken care of.

Really the next big thing is upgrading the tires. Do that and you’ll need the larger aftermarket sway bars, and I would say both front and rear, not just the front.. The shocks will be a big addition in terms of ride quality too, and they go right along with the tires and shorter sidewalls.

You can do all this in any order. If you do the tires first you’ll get an idea of what the body roll is like and that might have an effect on your choice of sway bars. The shocks will help you right now. If you do the sway bars first your car will probably be tail happy/oversteer until you do the tires, but really unless you go custom there’s only a couple of choices and they’re all similar sizes.
