FD RS/RZ Brake Caliper Seal Kits - Where To Buy?

[lockwood77]

I need to replace all the dust seals on my brakes courtesy of some trackday action. As I have a 1999 RS FD, that means I need the different sized piston kit for the larger brakes.

I think John at Atomic Rex supplied my last set, anyone know of other places that can supply (or a part number so I can ask around?)
