I have had good luck with my SP Performance drilled and slotted rotors with stock pads and calipers and braided stainless steel lines from Independent 4x4. When I changed out the stock pads and rotors at 70k+ miles the front pads had, probably, 70% life left on them and the rear had a little less. The stock pads are notorious for lasting a very long time. I'm at 112k right now, and haven't checked the pads since I put them in, but I don't think that the drilled and slotted rotors are wearing the pads excessively. The VX is a heavy little booger, but I can't push the thing hard enough to tax those rotors. I got them because they look cool, IMHO, not because I was going to race the VX.
