Thanks Merv
I think my problem is a little different as without the spacers which are 15 mm thick, I probably wouldn't have guard clearance issues.
All I can think of is that the inner face if the spokes may need machining back to provide relief from the caliper. I'm just not sure how much of this can be removed without weakening the wheel.
If I can find out manufacturer, I'll ask the question.
I don't think they are Dragways as Iva suggests as their website infers that they're made in Australia. They're stamped USA.
