Bumper problem on wheeled vehicles

[[WW]Hammer]

Hi!

I´m working on the german MAN gl Series of all-Terrain military Trucks. (as shown in following picture)


As all-Terrain Vehicles, they have very moveable axles, similar the the chezch Tatra truck released by the csla campaign Team.

Well, the problem is: I want a bumper Setup as these Tatras have, but when i edit the buper strenght in the config, the Vehice nearly kisses the ground in the front, but the rear wheels stay where they are an thier bumpers are as strong as before.
I also tried to move the center of mass (right?) to the rear, but this doesnt seen to be the problem.
Sadly i´ve also not been able to contact the author of the tatra´s or to look into thier config files - they are binarized.

So my question is: is there a different variable to set for the rear bumpers? or is there another way to solve this problem?

I hope you can understand which problem im trying to discribe!

Thanks in advance (and sorry for my english ),

Wow nice trucks,but where is that screenshot from? Doesn't look like OFP ground texture?
Sorry I can't help much with the bumpers,only thought I would have is by making the front real light in mass...

You said you tried that? But did you select in O2 where it "doesn't" apply mass to all areas and just lighten the front?

Ingame pics will come soon, at least i hope so!

Well yes i tried alot with the masses, the rear Bumpers remain as they are... ***
