The basic mechanics of these cars are just that with rod and cable brakes that were produced by Girling are more than adequate for what is a very lightweight vehicle.  The steering is not the more modern rack and pinion but again perfectly adequate.  The suspension is heavily based on that of the famous Model T with just one spring at each end of the car with lever arm dampers. Ideally, some leaves would be removed when building or checked if restoring the car as it is far too firm once the heavy steel body is removed.  Don't expect precise road holding similar to modern cars as this design was first utilised in the Model Y 8HP Ford in 1932 which though perfectly adequate for a light weight family car is not so cutting edge 90 years on.
