Physics Swapping Physics Between Cars.

Late to the party, but if you want to swap physics, in particular, the suspension, these are the key pieces of information that you need to figure out and match:

1- Suspension type.
2- Front and Rear suspension natural frequencies.
3- Critical damping force.
4- Damping ratios for both Bump and Rebound, slow and fast.

You are still required to choose a donor car with similar characteristics to the new car, that is:
-front weight distribution,
-weight,
-wheelbase,
-timeframe
-downforce tier

You can obviously get away without perfectly "similar" characteristics, but for each of the list above, the characteristics that don't match, you raise exponentially the complexity of the task.
