RE: 4WD FG MT?
I don't think it's lack of interest, but WWS is a very small company. I think they realized that production and distribution an own 4wd is beyond their capabilities. And it is known that FG is working on an all-new 4wd, not a conversion, as well. Even though the release date is a miracle (as are technical details), when the FG hits the market there would be hardly any room for WWS's car.
Btw, the WWS 4wd was never designed to run Bigfoot tires. You wouldn't get the gearing necessary for those big meats.
