[JSPERFORMANCE]

I never use "cheap" parts on my vehicles. I went from the NAPA brand O.E. replacement to the NAPA brand drilled and slotted rotors. The truck used to warp the solid rotors after one season of towing up and down the turnpike and now this will be my third season of towing with the same drilled and slotted rotors and still they have no problems. Now the fact that the warpage has been eliminated tells me that the holes and slots are contributing to an increased capability to dissipate heat. These are real world results not someone elses opinion on a web site.
