Stop in for a cup of coffee

I did... the wheels were ordered based on the specs from the rotor manufacturer. Amd the measurements to clear the fender wheels. All that stuff was spot on. Wheel specs say they’ll clear up to a 70.6 mm center bore. Rotor is a 70.3mm.Problem is, the wheel tapers down, they don’t have that on their spec sheets and a call to their tech services where they pulled up the cad file. It’s a stepped taper. That’s where it’s bottoming out at. But that step holds the center cap in. So it’s either the hub on the aftermarket rotor is taller than factory or the wheels weren’t machined out correctly. But I’m leaning towards the former. But trying to find factory specs for the rotor is proving challenging at best.
