Correct spring rate for QA1 coilovers

No, you can'[t raise it up. There's zero room between the coils to do that. If you tighten the spring nuts any farther, you're going to have a solid spring on the front. You think it rides bad now..........

You need new springs. Those are either worn out or the incorrect springs. Look how far the spring nuts are screwed up. I would take the springs off and see if there's a number on them. If not, I'd get in touch with QA1 and see what they say.
