improving ride quality

[thebluepearl]

Evening all, some of you may have read my little project thread on here and be upto date with what's gone on but if you've missed it I have recently lowered my hdi d turbo by 30mm but believe I fitted petrol springs derived from a zx so am now closer to 50+mm on standard shocks, im looking to improve the quality of ride as it now makes her indoors feel sick but don't want to compromise the look what do people recommend?
New uprated shocks?
Diesel lowering springs?
Bin off the Jin lung budget tyres and get toyo proxes

Any ideas and help greatly appreciated as i would like it to be comfortable instead of really crashy
