Softening ride on 93 defender

[fender22]

Have a 93 110 wagon. It actually handles and corners really well but I notice is pretty hard over speed bumps etc. Haven't had a chance to take it off road yet but wondering how it will go on corrugations. I don't intend on climbing boulders or anything, mainly light off road.

Just wondering if I could soften suspension to make it better for everyday driving? Does this mean a shocky change or springs or both? What is the benefit of having firmer shocks vs softer?

have you investigated (tried) lowering tyre pressures ?

(the placard pressures are wayyy to high for me I know)
