A 225/45/17 will rub. If available, you are better off getting a 205/40/17 when the 215/40/17 is not available.
I have had 3 sets of Dunlop Z1 followed by the AD08. The AD08 is $300 a set more and IMO is not worth the extra money. Given the choice again I would go back to the Dunlop. I have looked at my lap data over the course of many events on Dunlops, Yokahomas and Nitto NT01s and while you can clearly see the advantages of the R-Comp NT01s in the data comparisons I am extremely, extremely surprised to see the disparity on R&T test between the Z1 and AD08 as my data and lap times so them as equals. Grassroots motorsports has done tire tests before and the two were much closer.
However, since I'm not going to be tracking my street tires anymore I see no reason to get either as you will never, ever use all the potential grip on the street - even driving hard on twisty roads. Therefore, my next set of street tires will be either the Continental DW or the brand new BFG g-Force Sport COMP-2. IMO the 300+ tread rating (compared to the 180 & 200 of the Dunlop/Yoko) is well worth the tradeoff for the street since you will not be using the full potential of the tire. If you have done a lot of tracking you understand that those that say "but I drive the canyons hard" are fooling themselves if they think they are using more than 80% of the tires true grip.
