** UPDATE **
After 2 DE's and about 2,000 street miles, the Cquence rotors and RBC Redstuff pads work and look fine. Firm initial bite, no fade, and very low dust. Wear looks very good.
I have three more DE days planned over the next few weeks so I'll inspect and post an update in about a month.
BTW, these are the standard '99 calipers which were painted by the PO.
