The wheels took just about an hour and a half or so to install. Cost on the wheels is about $1,400 and about $1,200 for the tires. Total package is just under 3K. Both front and rear wheels are 9", although the rear tires are 275's, as opposed to 255's up front. The Nitto Invo's are pretty quite for how low profile they are, and they are not directional so they can be rotated side to side. Handling is great, they stick well. No rubbing at all, even with the suspension lowered down. Ride quality did go down some which is expected going into a low profile from the thicker stock tires. Car is still quite, but you do feel a little bit more of the road. Overall I am happy with it. I sacrifice a little ride for the looks. It's not much.
