I've been happy with it so far. I don't haul, load down heavy, or offroad with it but for regular street driving it seems to be nice. No more bottoming out over grocery store speed bumps. With new poly bushings slowly going in everywhere it handles much better too.

 

A saggy one sided rear disco 2 isn't new, both before and after lifts.

In the leaf spring world spacers are made to take up the sag, cruisers are also known for a one side rear sag. Should work just the same for the disco 2 coil but I'm letting the little lady put a years run time on her tf 3 inch lift kit before I put in a passenger side rear spacer so hopefully she'll be good and broken in by then.
