car and grip

Hi,
I would like to set up a simple car, I have use the wheelset on the racecar.mesh, and motor to make it move.
It works, but the car does not grip to the ground and balance too much even at low speed.
I have set a mass of 1000.
What am I missing ?
I have try to play with different settings for the wheel but in vain.

Also, what driveShaft is for ?

Did you try to lower the center of mass or changed the suspension parameters?

I use for a 1750 kg car the following suspension values:

SuspensionTravel = 0.3
SuspensionTarget = 0.0
SuspensionSpring = 7500.0
SuspensionDamper = 0.001

(just for clue)

Thanks I have change the center of mass and it seems to work a bit better now, also I had to lower the stiffness factor to slide more instead of balancing the car.

I have another problem now, my track is loaded as a static body with triangleshape. My car as a body as well with triangleshape, the collision works only on the ground of the track, but not the walls.
It works only if I load the car as a basic shape instead of trianglemesh.
I am doing something wrong or is it simply not possible at the moment to calcul these kind of triangle shapes colliding ?

You right, Triangle and Triangle collisions do not work. You can mimic it with a compound of shapes; primitives or convexes.
