| The race disks are cast stainless steel, which is what's on my bike. I use the Bendix carbon matrix pads with great results. Highly recommended, better than cast iron rotors. Cast iron used to be the top choice for discs and was used extensively in racing. Now, the cast stainless Brembos have replaced them. Still, if you need a set of new cast iron Brembos, I know Tim at MotoDesigns got a set on the shelf, 01904 623 421. |
