center caps for cup 2's

You are right to be concerned about using multiple spacers -- unless all are hubcentric.

I'm pretty sure the pair of 6mm for the front was $100. They did not have to be hubcentric, though, in my application. Hubcentric would have been more. (The 8mm spacers for the rear were over-the-counter, aftermarket items and cheaper.)

The aftermarket brand was H & R. They made 5, 8, 10, 12, 15, 20 and 25mm spacers for a 5x100 pattern. Perhaps, they make the 10mm version for your pattern.
