1st autocross run.
Not sure if you're still at this ride height, but that's too much altitude in the rear, and far too much arch on the rear springs for autoX. You shouldn't be able to see your leaf springs hanging down below the body of the car, and ideally your car should sit dead level. Not the best "look" for a musclecar, but the less rake you run the better you'll handle.
I'm running AFCO 20231M leaf springs. They have a reinforced front section (similar to other performance springs), but they sit with almost zero arch in the back. That really limits the side to side travel. And, lowering the tail end will change your wheel weights up front, so that should help with the front body roll as well. I know there have been a few folks with Dusters that had issues with the Hotchkis springs, not sure if they've addressed them or not.
The 20231M's are 121lb springs, but I run them with a E-body rear sway bar, which is 7/8". I still have it adjusted to the lightest setting of 3, seems pretty decent at least out on the country roads. I'm pretty happy with what I've got, but I'm sure I still have a decent amount of tuning to do once I finally get to a track. Next spring rate up is the 20231 at 142 lbs, but I think that's going to be too much for an A-body with a sway bar.
