[1.53] How to increase friction more than 1 ?

[greg2fs]

Hi, I need to increase the friction of my vehicule because in reality it would have crampons.
I thought I can go to the contact callbacks and add a force in the contact point in direction of the contact normal and proportionnal to the contact force but it doesn't seams to be a good thing.
Could someone tell me how I can do that ?

Thanks

Not possible ?

Shouldn't just setting the friction to wanted (>1) value work, I thought it isn't limited to one?

the Max friction value is 2 in Netwon, whic is way l;areg tha anything in real life

Can't I use a function like NewtonMaterialSetContactTangentAcceleration to eliminate "sliding" ?
