It's really hard to actually warp the rotors. Most likely, you have pad deposits on the rotors.
That being said, if the rotors have a fair number of miles, replace them. You can also possibly have your rotors turned to clean and smooth . The min thickness is on the edge of the rotor.
Rotors arent that expensive, so turning may not be worth it anyway
I highly recommend Meyle drilled rotors. I used them for several years of tracking and never had any issues with cracking around the holes
What pads are you using?
It is a good idea to cool your brakes after a session. If you can't get a cool down lap, drive around the pits and/or access roads for a couple of minutes, trying not to use your brakes. You should not be going very fast in the pits anyway
YMMV

I agree that rotors rarely warp, but I also disagree that drilled rotors don't crack. If you are running the car at more than a moderate pace with decent tires and track pads, you will start getting small cracks from the holes. Hell my slotted rotors have tons of cracks or heat checks, but so long as they don't reach the edges, nbd.
As to the OP, it doesn't sound like he is tracking the car. He should note, however, that slotted or drilled rotors won't improve stopping power in any way.
So, OP, go to ****************************.com, find whatever rotors fit your car, and select the cheapest ones you feel comfortable with (perhaps ate, meyle, sebro, etc.)
