Anyone know of good factory replacment cross drilled slotted rotors?

And I'm sure they look great!

No BS! Do the research yourself and you'll find that guys who actually DO drive their cars hard have problems with cracking. And these aren't measily little A-Body guys, these are guys driving big-time cars, very hard. I won't ever run drilled rotors, ever! It's not worth the chance. Now, if all you do is daily drive your fancy rotors and look cool, odds are your rotors willbe fine. But, as the OP stated, he wants to drive hard.
Dont doubt what your saying a bit. One thing though, the cars these things are going on,3200lb A bodies, and the calipers they are equipped with,REALISTICALLY, are not capable of generating the heat or clamping force that would cause the cracking in the first place. Yeah I bet you are hearing and reading about high end stuff killing rotors especially when the cars in question have 13"+ in rotors and 4,6 and even sometimes 8 piston calipers and weigh between 3 and 4k lbs. Those things create HUGE amounts of heat and nothing but the absolute best available materials will do. OK back to reality if you guys are gonna get new rotors might as well get the 11.75" while you're at it.
