It only rubbed once on my way home, but just slightly. I was at about 60mph when there was a sudden change in road height coming off fresh pavement. It was a pretty significant drop so other than that, no rubbing anywhere else. I was going to roll the fenders anyways. I have to wait until I get back home in March, I don't have access to a fender roller out here in Augusta. But I might just do it the old fashioned way, with a bat.
The tires aren't small at all, 235/40/18. They have a slight stretch to them, but just barely. I'm telling you, this is the perfect fitment and tire combo for the RZ. It also comes in 18x9 +45 which is slightly more aggressive and will definitely work. I was going to get these at first, but decided against it thinking it would've been too much poke for me. I have SPC rear camber arms, but I adjusted them to stock specs knowing I wanted an aggressive fitment. Once I got the wheels I wanted, I was going to make adjustments as needed. So I think I'm sitting at -2 in the rear, I'm not sure.
All I have is my camera phone so the picture detail isn't going to be all that great. As soon as the sun comes up, I'll post better pics.
