are cross drilled/slotted rotors lighter then factory ls1?

I have a hard time believing that drilled/slotted rotors WONT warp. Anything drilled is more prone to cracking, and the drills and slots take structural integrity away from the solid rotor, as well as cause them to heat up faster (less material). A blank is always going to be the best choice for braking performance and durability.....but if the slight trade off is worth saving a little weight I guess it's worth it. I can't answer how much less they'd weigh, maybe google it?

Here we go again
Check out their race cars that use iron rotors, you will see slotted rotors, but not drilled. While you are at it check out the major name brand brake companies and what that have to say about track use with drilled rotors (or what some say about drilled rotors in general).
Drilled rotors used to be useful back when pads expelled gas, modern day pads don't though.

Because god knows that car companies never do anything blingy to their cars! And all those cars when raced use cross-drilled rotors. Wait... no, they don't!
Why does this subject come up a million times over? It's physics people... Drilled rotors offer less mass to deal with heat. They offer less swept area for the pads to contact. They create tubulence in the vaning of the rotor. You see no race cars (where performance sort of matters) running them for those reasons. Yeah, you see some street car with them, but then again I see Z06's come with one brake rotor running backwards too-----direct from GM.
