Thank you, I think it looks really good!

I think from the tire being to wide for the rim.

I unknowingly blew away the photo's in that post I referenced above (sorry about that) so I added a couple below and also put more in my profile. I have the 325 Invo's and they fit about the same as yours. No tread sticking out of the fender and just a little of the sidewall. Absolutely no rubbing issues at all. The Nitto's tend to run a little narrower than most other brands which probably explains the similarity in fit. The car handles much better than with the stock sizes and the traction is a definite inprovement. I also like that the wheel wells look properly filled now, something I thought was lacking with the stock wheels and tires.

i thought about this long and hard also..then decided to stick with stock wheels because the car is still kinda unique...so i just went with stock size tires kumho ecsta's, and they are a bit wider than the stock GY F1's

good luck with choices

My fronts are 18x9.5 however, a 56mm offset... what are thoughts on running 275/35/18 on these wheels on a Z51 with stock fenders?

I like this size. I have 245-45-18 and 305-35-19 on my 2008 base model-but I wanted to go with a bit wider tire because I will be driving at high speeds here on the autobahn.

I'm jealous of the autobahn travel! Better drivers and better road conditions than the northeast portion of the United States....
