kind of a perspective on the difference:
"If you were to draw a circle on a piece of paper with a radius of 57.50 mm, it's diameter would be 115mm. Now use the same center of that circle, and draw another circle with a radius of 57.15mm. That translates into a diameter of of 114.3mm. the difference is SO small, that the two circles almost overlap each other. we are talking maybe 2 to 3 thousands of an inch here. .70mm is less than the thickness of an ATM card, or a credit card. In fact you could not even fit a credit card between the two circles because the tiny gap is half the thickness of the credit card.
Assuming that the aftermarket wheel's center bore matches the vehicles hub perfectly, as that is the load bearing assembly, and not the lug nuts, or studs then I can't see an issue as the difference is so minute. It wouldn't even be worth machining the mounting holes of the rim, as it would be such a tiny amount of material to remove."
