A big factor is the tire size. What size tire do you want to run? It's really easy to figure out. Once you decide on what size tire you are going to run get the diameter. Then measure from the ground to the center of your wheel well, subtract the diameter and that is a rough estimate of how low you can drop it. Other things to consider are shocks, steering components, and bump stops that limit suspension travel and may limit how low you can go until you modify or move them.
