Should not need to tune tyre pressures for ride quality. Set the tyre pressures for optimum contact patch, speed and stability in fast corners or rapid changes of direction. Then set spring rates and then damping rates for ride and handling. For good ride best to have a significant rising spring rate with a soft initial rate to take out the road surface degradations then stiffen up over bumps and with load. Then tune the dampers so the 'knee point' in bump is such that the low velocity bump damping still controls handling but the valves open to give ride comfort.
Q? So is the ARP4 suspension set up for track or road?
