I looked them up and noticed they're not cross drilled. I dunno what difference that makes. I'm wanting to replace mine too.
Just to correct the misinformation about drilled rotors......
The purpose has nothing
to do with cooling (that's the job of the "fins" in the center). It just looks that way so people make their assumptions.
The reason for the holes/slots is that under very hard braking, as the surface of the pads heat-up & wear, they produce gases that try to "float" the pads off the rotors surface. This "opposing" force effects braking performance.
So, the holes/slots allow these gases to escape as they go past the pads.
Thing is, you're really unlikely to be in that situation driving your truck
AND the holes at least, if done improperly, are a source for cracks to form around their edges. Plus you shouldn't resurface drilled rotors because it removes the chamforing from around those holes
They're not necessarily a bad thing, just a questionable decision you should be aware of....
