Looks sharp Jim, really like the aggressive tread on the Nitto's. The black rims should really make it look mean.
Sue, I think you have to be careful on going to a darker color for the skids. Even with Gatorback I gotta believe you could end up with at least 2-3 different shades of dark gray/black going on due to sun fading / materials / treatments. My thinking there is that you have the grill which is pretty much a matte black, the plastic cladding which is (insert color here), and whatever color you paint the skid. If anything I'd go lighter, maybe even to a medium silver/gray, somewhere between Ron's original light silver and the eventual color of your cladding. Just my $.02.
