Re: coys and backspacing issues
I assume you are talking about the C-5 wheels from Coys?
These would be my choice: 20x8.5 with a 5.25" BS. 20x10 with a 5" BS. The problem,... is getting Coys to send you what you order.

Re: coys and backspacing issues
The rotor grinding is minor really. its just a matter of beveling the end near the dustcap. It is only an issue with the HD rotors. Could be solved by using a space on the centercap, but I chose not to go that route. Doesn't take but a few minutes.

Re: coys and backspacing issues
If you go with 15's, be prepared to grind on your lower control arm, or have the tubular style, I went with them because they had them on sale, but damn it was a pain. Go with 17's or 20's. just my .02
