They are able to take a pretty good amount of abuse with the right pads, and the oem floating system is brilliant at allowing thermal expansion without the typical drawbacks of floating bobbins.

If you need a better brake setup despite using appropriate pads and oem discs, then you need an aftermarket brake kit from any of the reputable companies.
I just went to the track for the first time with Project Mu Club Racer pads and Castrol SRF. After 10-12 minutes, the brakes would start to vibrate. A few easier laps would reduce the problem and they were perfectly fine for the next session. I am overheating the rotors correct? The thermal expansion is creating temporary axial runout in the rotors?

No pad transfer on the rotors...
