That's a really good price! I sell the brembos too, but personally won't use them because they are cross-drilled and tend to crack more easily after a while. The good thing about the AEM's is that even though they are cross-drilled, if you get them through RRE, they usually can get AEM to warranty any problems with the rotors.

PowerSlot will also take care of most problems with their slotted rotors, so my main debate is between Powerslot stock size rotors, resurfacing my stock rotors (cheapest), or AEM big brakes (harder to install and costs a lot more though).
