If you're getting a "bang" like that you need to find what's causing it and change it. That's not right, it's not a symptom of your torsion bars or shocks. You're probably bottoming out your suspension.
Yeah, that (bottoming out due to being too low) is possibly what it might be. I think the front is set low also I need new rear springs too. Those are next on my to-do list. Once I get the rear springs (which I should soon), I'll reset the front end and do an alignment again. I know it's lower than before my upgrade because I can't fit my jack underneath the car now. I'll fix it soon.
