+1 to R1 concepts. I have their drilled/slotted rotors (factory diameter) and got hawk ferro-carbon pads from them. Great company to work with, and they custom make (so they say, no reason to doubt them) each order when placed.
As far as performance, you aren't going to notice a difference from stock rotors unless yours are in serious need of replacing. The looks is what you're getting, and they look great.
Other Ebay companys may be a bad idea. I wouldn't ever go for the cheapest price, as its probably the cheapest product.
I've had these for AT LEAST 30k and no issues.
