Lots of space at the UBJ. Currently the limit of steering stops the tire about 1/2-3/4" away from contacting the frame rail. The next closest interference is the tie rod to the wheel. Once I have a wider wheel, the tie rod would likely contact the wheel, but the tire will contact the frame rail and pre-maturely limit steering before the limit of the rack. This would prevent the tie rod from ever contacting the wheel. Almost a happy coincidence. This has absolutely zero to do with the HDK, it's a result of my high offset wheels. Had I started with an HDK before purchasing wheels, I would have set it up with a narrower track width and sourced a set with less offset. It certainly would have opened up the available off the shelf wheels that would fit. As you know, finding +35 wheels with matching rears isn't easy.
