Mike..

Any spring will lower when weight is added. By adding the air strut, which assists the springs you are adding the ability to compensate for any load you might put in the trunk. Remember when you say 1300lbs springs that FE2 springs were designed to work in conjunction with air struts.

Please search on this topic as there is a ton of great information you don't yet have on which way is best for you and how best to achieve it. If your mechanic says it'* costly to put a $6 kit for an airline onto a strut..then you might want to shop around a bit more since the added cost will be in his pocket when you pay him.

Heck..if you bought Squirrelly a case of Monster drink he'd probably help you do the entire job except for alignment.

yup and when you go to put the new ones in its gonna look like there the wrong ones, its just because the old ones are all deformed from being under pressure for so long.

you will have to crank it down till it stops, then come back a week later and crank it down some more.

*edit*
Yeah, my total was $587.36, for Struts, Springs, Bushings, Links...

Ok, so I need an answer on how to install the air system AND the pump with all necessary equipment, can anyone tell me how this is done? and at what cost (round about) ?

honestly id rather convert to a strut system in the back i hate ELC just my opinion though

That is what I wanted to do, but everyone here is saying to get the Rear Air-Leveling struts and the system. I mean some air up manually but I do not want to do that, if I am getting Rear-Air leveling struts, I want the entire setup, not something half-*** (no offense to those who have it like that)

i say if you have struts back there keep them if you want it stiffer, install some helper springs inside of the rear coil spring it will take some fab work but alot cheaper than finding elc parts

Well see everyone here is telling me "get the rear leveling suspension" and while that all sounds good, I'd need the sensors and pump and all that for it to work right correct? From what I understand. Setting it up in a manner where I'd air it up myself would entirely defeat the whole "load leveling suspension" and leave me with struts that i'd have to air up myself and would never work entirely right as per intended purpose. Not that I am trying to question those gearheads and/or people that have done it, the entire idea just makes entirely no sense to me. I plan on doing Monroe Reflex struts in the rear which look far superior to most and I have found them at Advanced Auto Parts. I barely ever throw a LOT of weight in the trunk and/or back seat, so the fast-reacting Reflex strut would be beneficial for me i'd think. Someone who can technically get into it post back if you think this is wrong, and tell me HOW to set up the entire air suspension the right way so I can take it into consideration. Leaving air lines to manually air up is not really an option for me, as the entire "load leveling" part would be null and void.

youre right like i was saying earlier my car came equiped with th air ride crap to do it you need to wire it up including relay'* and sensors,airlines fittings ,honestly stick with what you have and upgrade to the monroe'* i could think of money spent better in other area'*
