I heard about Specialized Stainless at the Auto Fair(2009) at Lowe's Motorspeedway. There were some nice cars with their cards on them. I was just wondering if anyone had used their Stainless drilled/slotted champhered rotors? Here's the link:

They look really nice and are not horribly expensive, but will they warp easily? Would/do they work efficiently? Do they kill pads quickly? Thanks.
