i have king lows all round with kyb excel g's, 20mm front sway bar, 24mm rear sway bar, front strut top bar, polyurethane bushes right through out and 16 inch rims. ride a little bumpy but not unbearable since i know that all four wheels are staying in contact with the ground
(no offence to mr revhead) i personally havent had issues with my king springs on any of my cars past and present and neither have my friends who have used king springs, and they are a good alternative maybe not the best but that are still good product, and plus it entirely up to you as a person what product u use in ur car
