Is there a company that makes front drilled and slotted rotors for an 08 Silverado? My trucks only got 3.2k on it but the front rotors are already warpped. I took it to the dealer today and they turned the rotors, but honestly he did a pretty shitty job cause I can still feel the vibration, and I don't want to sit and wait another 2hrs for him to do it agian.

 

More than likely the pads are also tapered and that is causing the vibration. Your other options are new pads or let it eventually wear itself in.

 

Don't know for sure, but check with powerslot, baer, wilwood, and ssbc to name a few

 

Check Brembo also.
