Rims look great, and I agree that with a slight lowering, everything would look very clean. I suppose that's dependant on whether or not this vehicle is being used in the winter. Sometimes its better not to lower the ground clearance. I wonder if you'll notice and different in power with the weight gain. Let us know how it rides.
No rubbing whatsoever. Lots of clearance. I may do a 1.5 inch drop on suspension. As for the 40 lbs you wont feel that in performance its negligable. Handling is improved due to the lower profile side wall . A bit more road noise but thats due to the cheaper brand tores i baught.
