I'm not trying to talk you out of the 16's if that's the way you want to go, this is just information. My comment refers to a good handling street tire. The Mickey Thompson tire is a drag race radial you can drive to & from the drag strip in dry conditions, their description. It's also 27" tall. Hard to say how this tire would handle through the corners, and if the roads are damp/wet, your out of luck.
Most 315/35/17 tires are in the 25.7" height range. Still considered a tall tire for a 930 by some. There are a bunch of great handling dry/wet tire choices, that will also work as a track day tire. To me, 9x16's on the front and 11x17's on the rear look fine.

As far as 11x17 Fuchs, there are a few companies that make one piece, 2 pc and 3 pc wheels. I'm referring to 3 pc. wheels. Fuchs 6x16's (the only one that works) are used as the cores. The centers are cut out and drilled for 20 bolt wheel halves by a machine shop. You buy the inner and outer halves (new or used) based on the off set you want. You can have someone assemble them, or assemble them yourself. Using used halves and assembling them your self saves money. I use to buy used inner and outers for race wheels, and used inners and new outers for street wheels (if you want them to look new). You could start with used outers, then switch to new ones when the budget allows. Used 11x17's occasionally come up for sale.
I understand your preference to 16's over 17's, I prefer 15's. But , your giving up good handling based on the tires that are out there in a 16". I know some guys run race tires on the street, I personally wouldn't. I've driven our race car to and from the track on race tires (Hoosiers), no fun and easily damaged. Again, just my .02.
