First, have you checked the subframe mounts? Rubber will deteriorate over time reducing clearances to fenders and hood. It'll also cause excessive body lean and make handling sloppy. Check this first, before messing with springs.
Replace them with aluminum (many companies sell them) and you'll never have to replace them again. Plus it'll really tighten up the handling even on an otherwise stock vehicle.
The rubber mounts seem to be good visually... But wouldnt aluminum mounts be to harsh of a ride
