OK, I think it's time for an update.

I had a closer look at bullet. The btRaycastVehicle is actually a simpler version of our current CARDYNAMICS code. It looks like the usual bullet simulation speed is about 60Hz(there are some guys running it at 1kHz). So I think it's not an option to run the tire simulation in bullet.

My current plan is to keep our current wheel/suspension code running at 1000Hz and run the chassis/world collision stuff in bullet at 60Hz. This would mean to apply averaged suspension/wheel forces to the chassis. I think it should be OK as there is no truly rigid chassis in the real world. It should be even possible to move the suspension simulation into 60hz bullet world. Let it act as a low-pass between wheels and chassis.

The new branch(no dynamics integration yet, will see if i find some time at the weekend):
