Generally the front is set slightly harder than the rear to compensate for the slightly heavier front end, bearing-in-mind that the springs are the same rate front & rear, unlike coil sprung cars which have lower rear spring rates.
When I was young (a long time ago
) I did tend to set my dampers a bit too hard, but as I learned more about optimising suspension I realised that slightly softer enabled the tyres to stay in contact with the ground better.
Best thing to do is to set the car a bit soft all round, maybe even start on setting 1 all round, then drive along a road with some bumps and corners to see how it feels. Increase the setting to 2 on the front & try again, then increase the front to 3 & the rear to 2. Do this until the car feels at its best.
For a totally smooth track, wind them up more whilst competing and back them off afterwards.
If he back is too stiff the rear bounces out of line too easily and this can be a bit disconcerting, especially if you are driving quickly on a bumpy road.
Remember, the idea of adjustable suspension is to enable the damping to be set to keep the tyres in best contact with the road.
