Doesn't look like they're gonna work, not without major grinding of the caliper. I started by grinding off the cooling fins, that didn't give me enough clearance. Looks like I'd have to grind away a good bit of the "meat" of the caliper too, and I'm not brave enough to do that. Maybe they'd clear drum brakes (not sure if the drums have better or worse clearance than discs), and I think they'd clear with say a 1/2" spacer, or maybe a different backspacing. But as for the 15x8's with a 5" backspacing, they don't seem to wanna work with rear disc brakes.

Shippin em back today, and I have a shiny new set of centerlines on the way
