I'm probably weird but my car still has what I assume are the original rotors from my donor car which only had 38000 miles on it. Even if they are replacements, they are at least 20 years old. I figure that their quality is probably better than anything that I would buy now so I would like to make them last as long as possible. That said, I only drive my car 1500-2500 miles a year so they should last a long time even if I used more aggressive pads.
