Z51 flaoting rotors
This post
http://forums.corvetteforum.com/show...ke&forum_id=74
said you could get the Baer rotors without cross drilling for the Z51 package. That is pretty much what I am looking to use for HPDEs, except the rotors are not floating. My experience has been that flaoting rotors really help handle expansion caused by heat. Also, I think it is easier to replace the rotor when the time comes.
Is Baer my only choice for 2 peice (flaoting or not) rotors for a Z51 package? I'm also curious if anyone has ever warped a set of Baer rotors?

Just a guess.

Yup, the caliper is floating, so if your rotor is a little warped or unevenly worn, it isn't a big deal. However, at the track, heat is the killer. At one point we had calculated how much energy was actually generated slowing a 3200 lb car 100mph was, it turned out to be much more than I expected. So most of that energy is dissapated as heat into you front rotors. Obviously, all that heat causes the metal to expand. One piece rotors will warp and crack because the center part is firmly fixed in place by the wheel, and the rest of the rotor is trying to expand. I used to go through a set of rotors in a weekend when I 1st started going to HPDEs, becuase they were warped so badly, they couldn't be turned. Floating rotors are mounted to the hat with bushings and have a little play in them to allow for expansion.

True race rotors are floating. Usually the hat is aluminum and the rotor steel, and they obviously expand at different races. The slot in the steer mounting bolt allows the hat and rotor to expand without binding each other up.
Even in solid steel rotors, the friction area is heated much more than the center, which causes some strange heat shock, causing cracks to form more quickly.
