Same wheels! Remember that the wheel/tire tech of the day was what Senna had to deal with, so feel free to take part in a crazy thing I tend to call "progress" and get the wheel of your choice, and tire that best suites your driving style and go! No need for any suspension mods, just do the wheels and you'll be a happy guy.
As for "why not powder coat the calipers…" thought - my change took 10 minutes total and looks great. I've seen some stock caliper coat/color jobs I most certainly did not like, and its not easily reversible if you don't.
