Perhaps I'm late to the party but I'd like to contribute. I'm running 17x8 TC105X in the front and 17x9 TC105X in the rear with 2017 BRZ with stock PP Brembos. They fit fine on my car without spacers.
I measured the clearance. potential points of interference: it's about 0.2 inches (5mm) from the barrel of the wheel to the front of the caliper, and 0.2 inches from the spokes near the center to the back edge of the rotor.
