Thank you aftcg, something tells me I'm redoing at least one pair of rotors ......arg
One other thought could the dust I'm getting now be "left over" from the OEMs?

Checking general info on line I found this from a racing rotor manufacturer:
"For high performance applications the slots and vanes (if curved) should always angle to the rear. The curved vanes must sweep rearwards to evacuate heat from the rotor, likewise the slots must angle rearward to evacuate brake pad dust."
These pictures as well. Marc let us know about the specifics for these rotors. My fronts and rears do not rotate the same direction currently.
