its odd to me that the SLK only has the 2 midway, my XF had 2 up front and 2 in the rear. If the defoulers will work then I will gut them and move on. I am so happy with the car. Shifts great, only light is BAS for some reason but that is no big deal. I cant believe I have wasted a month trying to clear this code but it is behind me now, in the morning I address the top. I have yet to try it. I am going to put some miles on it and drain the trans/convertor again. LSD diff is my next project. I will touch base about the website, thanks
