I did anthracite grey + glossifier and they look pretty good. Just need to do the last two wheels and get tires.
I'm reserving judgement until I see them on the 5. I think the 5 spoke Rx8 wheels might bring a little balance to all the curves of the 2nd gen. I have yet to see any 2nd gen running them.
I'd say they'll look good as well. I know my set up is not everyone here in the forum favorite but I strongly disagree and feel that my gen 1 MS3 wheels look great on my 2nd gen. Those wheels are also very much straight and squarish looking. Just my opinion.
