I have the cryo-slotted rotors and hawk performance pads. They do squeal but the increase in braking performance is notable, and they have yet to warp at all, unlike the stock rotors which may as well have been made of plastic the way they warped on me.
I'd probably buy the cryoslots again, although when I need pads I'm probably going to go with ceramics, because I don't think I'm going to be able to get my wheels clean without repainting them at this point.
I have Brembo blank rotors, work very well!!!!! I have Hawk pads also, there's a noticeable gain compared to stock. I wouldn't get slotted ones if you 4-wheel it in that rocks/dirt or w/e may get stuck in the slots and mess up the pads, not sure if it's possible, it's just what i've been thinking.
