Gravy, Check out the link I posted above for the mattracks. Its four tracks, one on each corner, VS 2 tracks, one on each side. Pretty cool track system, but very expensive. And I still don't think it would work because if you turn, they would bump into each other on the inside wheels.
I'd forgotten about those. Very cool, but as you say, probably not the solution for a PT.
