X2 on Calmini coils drooping with age.
Just changed out my 2nd set ( went OME )
Calmini shocks are good, cross menber is fine but as stated already..NOT related to Diff drop at all.
Unless the Calminin kit is SUPER CHEAP...you are better buying OME coils and doing the T/B crank....
...and use OEM shocks...thats a few beers less than $200 if ya do it yourself.
Depending on how much lift you want/go for...be prepared for you CV boots to shred
pretty soon after lift...as they become "used" to being at a given angle...and many have bust theirs
soon after lifting.
If you need info on OME coils..go here for a great run down:-
