Ok I'm sure this has been discussed but I thought I would pass on this info. If you choose to use Hawk brake pads ( I love them) you will have to drill the holes for the pad sensors, should you choose to run them. I just used a Dremil with a carbide bit to make the provisions, and all is well. Since the wife drives the Boxster I need to have the sensors installed. You marrried juys will understand.
