Our trucks rotors are notorious for warping for several reasons:
1. Overweight with undersized brakes
2.
ADJUST your rear drums! In most cases, our rear drums are not adjusted properly - makes our front rotors do all the work to stop the vehicle -

3. Improper torque on the lug nuts cause the rotors to warp prematurely
4. Probably the most overlooked problem - IMPROPER break in period on the new rotors/pads
Contrary to popular belief, crossdrilled and slotted rotors don't do much, if anything for performance - baer.com see link below.
Crossdrilled rotors develop stress cracks, and for our application, are probably not the most ideal. Unfortunately, slotted rotors go through pads significantly faster than crossdrilled due to the clean surface you get with every rotation.

With what I have read, Brembo blanks or the Tundra upgrade are the two budget brake mods one should consider. With the above sources in mind, I would not be able to confidently recommend drilled or slotted rotors. But I guess everyone's situation is different. Some people think drilled/slotted rotors look good. Personally, I have weight reduction in mind and went with the crossdrilled rotors. Saved two pounds in rotational mass.
Current setup:
1. Brembo crossdrilled rotors
2. Goodridge G-stop stainless steel brakelines
3. Rear drums adjusted
4. Proper torque on the lugs
5. Proper break in period applied to new rotors and pads
ZERO issues. Good stopping power.
