ultimates I hear are supposed to be great pads. They have a broader range of temperatures than the Axxis Metal Masters, but most likely have shorter life than the oem type pads. Try www.cobaltfriction.com, they had great service and a decent price on them.

and most of the time people don't "warp" rotors. They have uneven wear and the rotor runout ( think thats the term?) goes off spec or other factors cause steering wheel shaking (unevenly torqued lug nuts). But rotors dont warp because of brake pads, its driving style and the such. You probably wont heat the rotor high enough to warp them unless you really do track/drag strip time or something stupid on the street
