I have had NAPA ceramic pads on for 500 miles or so. My wheels are still cleaner than just backing out of the driveway on the factory pads.

I can honestly accept that as a FACT! It seems that is about all you have to do to get brake dust on the wheels. Today, we drove into Houston and a couple times I had to hit the brakes on the freeway driving in and I kept saying, "Come on people, you're getting my wheels dirty"!
