I've seen people with 20's and sprint springs. The issue is not just wheel diameter and drop. You need the correct offset and tire size too.
For example, I have 19's with a 42 offset and springtech springs. the tires originally were 245/40/19 all around. The fronts rubbed quite often. So when it came time for new tires, I bought 245/35/19's. Rubbing was eliminated.
