I should have looked for a bbp 8.75 to match the fronts. But when I found a sure grip Richmond 4.11 complete for $750 I jumped on it. Just figured I'd put bbp rallye wheels on the front and sbp rallye wheels on the back. Easy enough to remedy. And I guess it's not important what size the rear pattern was, as I'm putting in another sbp anyways. But just thought it odd and wanted to see what you guys think.
