https://www.ezaccessory.com is the source for the spacer I used to put the front calipers on my SRT and NA, but remember they use different front hubs. the NA has the open hole and the SRT is the capped one. I need the 10mm to clear the NA, the SRT wheel would clear a 5mm one but the do not make one that thin that is "hub centric"
Also if you look at my former post you see where I painted my calipers, I used engine paint which is good to 500F. Buy AMG stickers off eBay and put the on, then get the clear engine paint and put on several coats, mine still look good, and my NA is a daily driver.
