I am having issues with my rear suspension, It sags with the addition of any amount of weight in the trunk like 70 pounds or more. whats best for a fix? coil over shocks? air shocks? or some type of stiffer springs?![Click image for larger version

If you dont have load leveling air bags, I would say new springs. Unless you haul lots of weight all the time, air shocks are not nesassary.

I do tend to run some large stereo systems in my cars, last one i had in the mercury actually caused the tires to tuck into the fenders, so i had to remove it. so improved suspension is my goalComment

So, maybe some heavy duty cargo coils are what you want, since the weight is part of the car.

No need for air suspension. Just get some heavy duty springs. Even junk yard pulls from a P71 wouldn't be bad.Comment
-
so air shocks= bad idea? and i feel that if i am replacing i only want new parts, so p71 springs are that much stronger? would they adversely affect my handling being stiffer out back than in front?Comment

im not at all used to working on a rwd v8 platform like this, I am and always will be a die hard honda fan and builder but i love my mgmComment

I've put a few pairs of cargo coils in the rear of panthers over the years and my experience was, didn't effect the ride much, but did flatten out the car a bit on highway onramps etc.
Just my feeling, I can't say how you'd like it. Good luck.

Cargo coils as in load adjusting shocks or is there stiffer springs I am not finding listed?Comment

Ah sorry. Old vernacular. 'Variable rate coil springs' is the correct term if'n I remembers correctly.

I think the rear springs from 1979 to 2012 work IIRC... so you could use wagon springs (your basic cargo coils) or order up some stronger springs to fit your car. To swap them out, you just need to unbolt the shocks and lift the rear of the car until the springs pop free... then just pull to get them out if they don't just fall out. Replace with the new springs and re-attach the shocks.
the interchange may stop at 2002 though. I'm not real sure on that one. police spec springs are stiffer as well. you can always spec out even stiffer springs. Though, to figure out how stiff a spring you need... about how much weight are you keeping in the trunk?

If you want to haul a lot of weight, order springs for a natural gas vehicle. They are heavier to deal with the added weight of the CNG tank in the rear of the car. I believe those are the stiffest springs from the factory for these cars.86 Lincoln Town Car (Galactica).

I have 140 of sand in back right now, in the summer its 4 12 inch subs and a 3/4" thick MDF box and ampComment

so about the same weight both ways.
yeah... go for the CNG rear springs like gadget said.
