02SKReX - This is one of the up-pipes that were produced for us by Brullen. It used to be a display piece.
damianq - We've got actually 2 sets of FHI 2pots w/ brackets. One is from a '97 Legacy GT, the second is from a '99 Legacy Outback. If your '99 RS was made before June of '98 these will use your existing pads. However it's the brackets that determine the pad choice; so you could just swap calipers themselves.
Those are front hub assemblies. Unfortunately don't have any rear set-ups left.
