Hi, i have some progress in my car now..:) i think it
was just some configuration that i miss out. Now i
have just some problems: 
- if i steer to much the car will be upside-down so
easily, great velocities the problem is worse.

--> change your rotation matrix, it can be a solution but it can
definitely change your car behavior


- The timestep that i pass to the ODE is the time
elapsed in the frame, so i got strange behavior in low
and high fps. 

--> this is something you should definitely avoid ni ODE try to have a
constant timestep for example 4ms!

--> If the time elapsed in the frame is 20 ms call five times ODE for
4ms



- and the main problem: can someone post a code to the
steer??? i dont know how to return the wheels to the
correct position without using this:

joints[0]->Set_Param(dParamLoStop, 0);
joints[0]->Set_Param(dParamHiStop, 0);
joints[1]->Set_Param(dParamLoStop, 0);
joints[1]->Set_Param(dParamHiStop, 0);

but when i do this the chassis seen to take a force
and jump a little.
