car suspension spring-damper??

[campa75]

Hi to all,
I have to simulate the behaviour of a spring-damper in a front car suspension model: how can I do it?
What class do I have to use?
Maybe "btGeneric6DofSpringConstraint"? Is this the right solution?
I tried to use this class but I have the doubt that it is not correct, in fact I think I should define a location (by a vector) of the pivot spring-damper and not a btTransform...who can help me?

Thanks in advance.

Anyone can help me?
Anyone can tip me off or give me an upright to solve my problem?
