I had DBA 4000XS rotors and they are very stout. I had issues with my Hawk HPS pads cracking a few times for no good reason though. Didn't feel like shelling out $800 more bucks on brakes for a street car so I went on eBay and bought the Powerstop kit. Good bang for the buck.
BrakeMotive is actually a vender on corvetteforum.com and they sell a ton there. Everyone is happy with them. I'm running them on my Z06 as well.
