God damn dude nobody's going to take the time to read all that ****! And what applies to a street car doesn't necessarily apply to off road either. Take into consideration that the biggest killer of brake pads on quads and dirt bikes is not actually just gradual, normal wear. They get put through much more abusive conditions than automotive ones typically do, and the drilled holes help to clean out all the grit from mud and dust that will get between the pads and rotors. The solid rear on my warrior warped from excessive heat (partially because a solid rotor like that dissipates heat very slowly), never had that happen with the drilled rotor. The 3 hour screenplay script you posted about them may say otherwise but I disagree with that, maybe that's true in the street world but you're talking about a different animal with this. We tend to travel at lower speeds, with heavier and more frequent braking, and our brake rotors are solid so they don't have the cooling effects that the vanes inside an automotive rotor do. Maybe that makes a difference, maybe not, but being that your article didn't mention a word about anything off road, it has no credibility to me in our application.
Believe what you will, but I can see very easily with my own eyes what the wear tendencies are of a solid rotor vs a drilled rotor when contaminants like mud, water, and sand come into play. All the grime that's left in the holes of my rotors tells me that they are in fact removing contaminants that would otherwise be accelerating wear on the pads and rotors. Among other examples, I just replaced the original set of front brake pads on my Suzuki dual sport, that's the original set of front pads with 18,000 miles on and off road. If drilled rotors accelerate wear for quads and bikes, they don't accelerate it by a whole damn lot that's a long time for a set of brake pads to last.
