A vehicle, ideally a "real" one, complete with fluids and used
Typical spring, bar and damper settings, and a range of springs and dampers
to explore alternative strategies.
Damper position transducers are not strictly necessary but, if fitted,
then they can be used to provide useful supplementary information (position
transducers can be potentiometers or LVDT's).
A crew and tools to carry out vehicle changes.
Ballast to represent the driver, but this can be provided.
If downforce is required to be simulated, then a means for attaching downforce
cables to the sprung mass.
All transducers (apart from damper position) are rig inventory items.
