The wheels are 20" Chrome Mirage DK1 5-Spoke Rims - 40 Offset
on Falken FK 452 245/30/20Y 8.5 width tires - the wheels have been discontinued.
I listed the car on Craigslist, fielded some inquiries, its hard to part with. So I still have it, wash it, drive it, and took it off of Craigslist. It has ~127k miles and runs very smooth and strong with no transmission or engine problems since getting the COPs & Gasket replaced at 66k miles. I've got some more pics of it with the ZR in my gallery and some ready to post where/when appropriate.
