Take a different spin on "You might get 10% more performance in repeated panic stops", that applies to much more beyond the break pads! Right after I got the X5 out of the shop, my wife's 330ci traction warning light came on. It has 80K miles, and I am afraid the DSC module, again, on 330ci. My wife does not know much about the car, and she had a "panic stop" on the warning light!
