I do know he had them made to that spec. Maybe he'll chime in.
Sorry for the late reply, for some reason I don't get notifications from turbobuick.
Yes, they were a "made to order" wheel. They are 9in wide in the front, 10in wide in the rear. I wanted a bit more of a lip in the front, but the wilwood hub put major constraints on the front lip depth. I got them to custom machine the front caps, which only gave me about an extra 1/4in of depth, but anything was better than what I was expected to have without the custom machined caps. Turnaround time was about 9 weeks.
