i'm about to order a drop kit, I'd like to do a 4 or 5" drop in front and 6 to 8" drop in the back. I have stock wheels and tires, 275/55/20s. I put a straight edge up against the tires and it doesn't look like they will clear the the fenders. I did plan on running a smaller tire, 275/45.

Am i going to have tire clearance issues lowering it that much? It doesn't look like there is as much room in the wheel wells as the previous models trucks.
