I have r1 concepts drilled and slotted rotors the pads sold in the combo. Tech says I have plenty of pad left and the rotors are fairly new like 30 k on them. I randomly get this really nasty brake vibration and the truck is hard to stop. I took it to one shop who said that the rotors are warped. Any ideas?

Either they are warped or your tires are cupping.

Does it only do it sometimes? Like after driving for a bit?

Try getting the rotors turned. I've never owned drilled/slotted rotors but I've had success with turning standard rotors to get rid of vibration when they are slightly warped. You can usually get them turned for around $10 each so it's worth a try.

The thing is I have had what i think is "cupping" on my tires esp the fronts if that is the tread wearing in a jagged frontward angle. I have never gotten a straight answer to why, but i think it could be the fact that I have been running the wrong bilsteins for a few dozen k miles. maybe its the low rebound setting on what i thought were the proper replacements but are actually for the standard tb. Think this could be the culprit?

No the runout hasn't been checked I am thinking about some suspension upgrades and the way I see it if it is the rotors I might as well just replace them with blanks rather than go through the expense of having the runout checked.
