Just got the mini wheels to go with the mini tires. Regarding the brakes fitment, I have not been at home to test fit the rotors and calipers in the wheels, but the inner diameter of the wheel near the hex is approx. 33.5mm, tapering out to 36mm at the outer edge.
The discs are 30mm so that leaves 1.75mm each side for the caliper, it will be tight but sounds like it is doable. Worst case is I will put the rotors on the lathe and "turn" them down a little lol (in diameter that is haha)
But I am questioning clearance towards the wheel inner face, because the hex is flush with the inner side spokes, so if the hex sits fully in the hex cavity, that leaves no space whatsoever between the disc and wheel spokes. If that is the case I might dremel the inside spokes a little to make room for the calipers. I will update once I do some actual test fitting.

edit:
Got to test the fitment of the mini wheels! Looks like it will be a perfect fit!
The steering linkage will need just a little bit of filing but nothing affecting the structure really. And the size is just perfect!
I think the brakes will fit tightly but should be doable. Will definately put the wheels on the lathe and shave some material from the back face of the wheel.
