Try to increase the mass of the wheels.




This is exactly what I've been doing, but it has a very undesireable side effect: with the car weighting only 1 unit and concentrating the weight at the wheels they tend to have a strong gyroscopic effect on the car i.e. during extended air times the wheel rotation heavily influences the pitch/roll of the car (wich, of course, should be kept almost unchanged in free-fall)

@EX Citer:

I'll try to reassemble the car body as two separate models with wheel junctions and lower structure in one and "decorative" upper-body in another and attach them with a phcon_ constraint so I can add proper weight to the lower part. Hopefully it'll get the desired effect.

Thank you all for your input
