Apparently this isn't new information to some people, but I thought I would post it up here. I was at the track last night, and met another S550 owner who used to be a ford tech. He showed me this little jumper plug Ford put in the traction/stability control system. When removed it completely disables both systems. I plan in cutting the wire, and installing a interior switch so I can turn it on or off from inside the car.
