Generally, the conventional LC springs and shocks do perform well. The coil springs have a limited life before they start sagging, that's how it's been since the beginning of the 80 series.
For coils, you have to do a bit of research. Some of those on your list are for AHC vehicles, at least the pink and the brown, possibly all P/Ns from -6A750 and up.
It's all about the length of the springs, and how much permanent extra weight you carry.
One tip is to look at standard springs for Australia, they have a bit sturdier suspension setup than in EU & US.
You can go one up on the left side, as the LHD 100 is heavier on the left (tank & driver). Otherwise you adjust that on the torsion bar only.
