As an update, I managed to knock off one of the screws holding the fender trim in. The tire was actually rubbing on the front top bolt and even with loctite, it's now gone. Also, if you roll the fenders flat enough, the top clips won't hold anymore. The tire can also rub on the rear bolt. All of this happened after I installed 305/35/22 tires to replace the 285/35's I had. The look is much more aggressive and the ride is better, but it started rubbing again. Since the front bolt is gone anyways, I'm just going to roll the fenders there as well and use adhesive to hold the trim on.
In a couple of days, I'm going into the shop to have new TPMS sensors installed. At the same time, they're going to align the car and I'll likely go w/ -2 camber up front and -3 in the back for a little more clearance. FWIW, my car is pretty low right now. It sits like Stu's car in the pic at all 4 corners. I've already just about maxed out the fender work that can be done without pulling (hammered down the bump where the rear door line is and everything). The FX is just not meant for anything too aggressive. My wheels aren't agressive and it looks like there's enough clearance, but it still rubs.
