Rotors are rotors, it really doesn't matter who makes them. Avoid cross-drilled and/or gas-slotted.
Yes and no... Definately avoid wasting your money on cross-drilled, slotted, dimpled, etc., rotors. But you have to realize that not all blank rotors are the same... while the design is almost always the same, or very close to it, there is a difference in the metals used.
I personally run Duralast rotors from AutoZone ($21.99/ea) and they have proven time and time again that they can stand up to the abuses of road course racing. You may notice that Autozone also sells Valucraft rotors for about $16.99/ea, and although they appear the same and have similar markings and boxes, there is a world of difference. I managed to badly crack one from just a month or two of street use with Axxis Ultimate pads... it's normal to get some light surface cracking with semi-aggressive pads like these, but anything deep is a problem, and this was not only deep, but all the way through to the ventillation section! Needless to say, these rotors would have resulted in quite a disaster if I tried to use them on a road course with real race pads. The Duralast rotors, on the other hand, have never given me any problem until I wore them down way below the acceptable thickness. Some of the more expensive blank rotors offer a lower rate of wear when used with aggressive pads, but it's not worth the money, IMO.
