Part of the issue is you have way too much spring up front. You are way over sprung for a drag car and no shock will correct that. You’ve already been burned once buying an effectively untunable shock. You can buy double adjustable shocks for about the same price as a single adjustable. Always buy DA shocks. I don’t know what the spring rate is for that big bar, but you have to take a bunch of weight off it (meaning pitch rotate the chassis) just to move it an inch. What I’m saying is (using made up numbers) that lets say your torsion bars have a 500 lb/in spring rate. That means to compress the spring 1 inch you need to add 500 pounds to it. The opposite is true. If you want to raise the front of the car 1 inch you have to take 500 pounds off the spring. It’s as simple as that. Now let’s say you change out the bars to 250 lb/in bars. Now it only takes 250 pounds off the spring to make it move 1 inch. That means is takes less weight to get the car to pitch rotate with the spring with less rate. To get the ride height back, you adjust the bars up. If it was a coil over spring car you’d just raise the platform the spring sits on to get your ride height. With out addressing the torsion bars, in my opinion you’ll never get what you want. You’ll have to chose between street ride comfort and track ET. With the percentages you posted above, I’d leave what you have in there and live with the ET.
