Imperative to ride comfort and design function that the SSL RS kit at the front has the static spring situation adjusted for exactly zero pre-load with no gap at top of rebound spring.
The main issue in achieving this is defining the static stub axle position. Damper and stub axle stiction plus lateral tyre movement hinder this which is why SSL instructions suggest fully greasing followed by drop with trolley jack without dampers attached to achieve a bounce. I found a compromise by dropping after full grease and just jacking back up a couple of millimetres when rebound springs should just lock up when twisted. Repeating this several times gives confidence you have a median to correct adjustment.
I certainly wouldn't leave as is just to satisfy rear. Doubt adjusting front would make that much difference TBH.
