I have a mid travel 4 seater honda v6 rail with 10" fox 2.0 emulsion coilovers in the back. When i go over whoops the bump stops are hitting. My springs are rated at 300 lbs and the nuts are tightened about half way down. Should i tighten them down more or get a heavier rated spring? Just cant get bigger shocks so i want to try to work with what i already have.
