XP12 in the front and XP10 in the rear. The heat range on those pads is quite a bit higher than the heat range of any fluid on the market, so your fade is probably coming from boiled fluid. Again, brake ducting would probably solve all your issues, but a more 'bolt on' solution like stainless lines or Ti shims, both of which will help insulate the fluid from the hot environment, should help as well.
