Model Changes in o2 not appearing in game

[DKM Jaguar 0]

I appologise if this has already been asked, I did search first but found nothing.

Essentially my model has been put almost exactly how I need it in O2 in regards to tracks and the positioning of the roadwheels (but I must stress not the modelling of the wheels themselves) yet the changes made in O2, despite clearly being shown in Bulldozer (see below picture) are not being used in the game after I pbo it to test it. I am at a total loss for why this may be. The wheels are incontact with the bottom track in my model yet ingame they are almost touching the return track and the track itself appears to have been stretched down...

As you can see, the two tracks are not the same..

Any help would be gratefully received, but as I said, I am totally puzzled by it.

BTW:  I know the model looks crap but I've seen a lot of people's first models looking a lot worse

are the wheels defined properly

Looking at the pics the only two things that I can see would effect the model like this are

podkolo points and land contact points.

The hieght diff seems to be the exact thickness off the tracks so maybe reversing the podkolo selections individually may help,

may not help either.

I have not yet defined the wheels, which in a way makes it more confusing, as it is just an ordanary part of the model , which it shouldn't screw with...  

It may be the landcontacts, now I am sure the exterior model is 95-99% accurate I am turning my attention to this kind of stuff.

Thanks for the help, it may or may not work but at least you offered help.   Many thanks.
