I installed cross drilled rotors on my 850 a while back - around 195,000
miles......
The best reason to use them - they don't cost any more than regular rotors -
is that, according to my mechanics, they've never seen a warped cross
drilled rotor.....! Heat dissipation is the most serious problem in this
arena and that recommendation was good enough for me. It may just be
"subjective" on my part, but I find the brakes to be smoother and very
strong with the new rotors and pads in place.....

| over and over).
