what about me?
Just kidding
RE: wheels - there are different limiter spacers. They are integrated with the tie rod ends on later cars. I took the spacers off the ends and used my OEM spacers on my car. You can do some measurements.
I read in one place the 3rd mount was for NVH. I could see it picking up the moment from the motor/ballscrew/etc... bouncing up and down ahead of the rack. It would be fairly easy to integrate, at some time, into an aftermarket K.
I can't remember what the old hydraulic rack felt like as I had the car down for nearly two years. The new electric rack is very light at a stop, and the car handles great at speed.
