hope this helps hammer, i too got the idea from some Porche guys i track with
i modified a "hidden hitch" brand hitch. i used the existing front mount, cut just behind it and made an offset to raise the bar to hug the bottom of the trunk. i also used the rear mount as it was, but ran the bar above it and again added a spacer to provide the correct offset. to add some stability, i added an angle bracket that bolts to the rear crash bar
my car is not lowered, so the flat bar is welded to the bottom of the square bar for the 1 7/8" ball. this sets it up so that the front of the trailer is just slightly higher than the rear.
