I wouldn't trust or use any cross drilled/slotted rotors sold on ebay. I went through a few sets on the viper and corvette in the past and either they crack or warp shortly after from normal driving. Later what I found out was pretty much all rotors being sold on ebay are manufactured in China using cheap mixed metal and substandard casting. There is a huge Chinese brake rotors/pads importer in Riverside, CA and most of the ebay sellers buy those cheap stock replacement rotors from them and machine and plate them locally. That's why most of the seller on ebay are located right here in Southern California. You should spend a few hundred bucks more and get the DBA rotors. Many people here don't know or heard DBA rotors but they are pretty well known in corvette, bmw and porsche community. They've been around 30 years and have been a supplier of BAER, Brembo and AP Racing brakes. I personally have these rotors on both of my viper and corvette and IMO, these rotors are the best bang for your buck. Check out their website and you'll know why they are top quality rotors. I believe there are a few vca as well as some ebay vendors sells DBA rotors. You should go check them out.
