any suspension tips?

I'm not playing dumb. What constitutes "improving the suspension"? If you're wanting to hook up for straightline use, 3404spdvaliant had good suggestions.

I set the Demon up for road work. I'm using Monroe Gasmatics which are an improvement over stock. Also changed bushings from rubber to polygraphite. Using anti-sway bars front and rear, which reduces body roll.

I had the front end set up for maximum postive caster which helps turn-in. A lot of positive caster ups the steering effort required. I use a cop car (Firm Feel) PS box.

To help keep the rear end in line I fabricated a Watts link. You could use a Panhard rod or track bar to do the same thing.
