Softest lowered springs

[water]

Hey all, just purchased a gs350 f sport and looking to do some basic mods (the mrs will get my current is350 f sport). Im posting here as i dont think the GS forum gets much traffic!

Anyway, are there any lowered springs which have the same softness level as factory? Love the look of the car however it sits a little too high.

Also, has anyone swapped out their steering wheel to a newer update model one, or does this fall into the too difficult basket?

Cheers!
