Chazz,
I seem to recall Racers Edge making the same product a few years ago (I can't seem to find it, but my car is equipped w/ them), as well as lunsford offers a Ti. version.
I think its awesome. I love the fact that I don't have any protruding material with which to get hung up on obstacles. I would really love to pick up the X6-squared kit in the future. I really like what you have done and will contiue to watch attentively as X-Factory grows and develops.
