I just have a need for larger rotors that have cooling capacity, such as being cross-drilled. My house is up a long, 7% + grade, dirt and pavement road, steep enough that a 2 wheel drive long bed extended cab truck cannot make it up the hill when it snows. 4 wheel drives are no problem but not a 2 wheel drive truck are a a problem. Anyway, we use low gear in the stick shift and automatics when we drive out downhill instead of using brakes but we have still noticed our brakes wear faster than when we lived in town. I think bigger rotors and better brakes would be a benefit for us. Thanks for the link as I lost the link I had for rotors.
