I had this problem too.

I didn't base my code on the buggy but I've got a box and four spheres.

That's how I fixed it. It took a while to get a good balance between 
too much grip (overturning) and not enough (skidding). My car still 
over turns sometimes which I think is because my centre of gravity is 
too high. And anyway, cars do turn over in real life, I know:)
