Hey all,

I have a 66 fstbk and I have replaced the rear springs, with stock replacment springs. Unfortunately, it still sags on the drivers side. So while I still have to replace the shocks, I am wondering whether I am suffering from a saggin A$$, and whether it may be due to a slightly bent body. THe rear end also squeaks. So what are your thoughts, and has anyone used a set of subframe connectors, with the chassis stiffener (like heidts or the TCP products). How did the frame setup feel after wards, any pics etc.

Thanks for the help and thoughts, I always get alot from all you guys (and girls ;&gt!

cheers

 

if your shocks are really worn new ones will lift it up a little...they lifted mine about 1/2" but my old ones were extrememly worn out.

 

hmmmm don't know how shocks are gonna raise your ride they are there to dappen the ride and smooth it out and not give it a tuna boat feel...but if you say so??? unless of course you have the load leveling shocks that alot of people put on these cars due to sagged out springs...and or air shocks can help...anyway as for the saggin' draggin' rear......make sure your shackle bushings aren't worn out and or missing ..meaning the ones that are in the frame as the ones in your springs are new I assume.......also it'll depend on the quality of the spring you bought...the arch may be different one one of them if they are cheap repo's....swap side to side and if it still remains the smae there is a problem with maybee where it mounts......where the u-bolts are there are rubber spacer/spring isolaters that the springs fit into..not sure of the correct name but make sure they are both intact on each side and not sure if your car has been restored but frame rails rusted out can affect mounting integrity and location

 

never i repeat never ever use air shock on a mustang dont ask me how i know, my 72 had them punched a nice hole through the floor of the car
shock support absolutlely none of the vehice weight they are there for one reason to absorb the shock of the bouncing of the wheel

 

they were the kyb gas-a-just...and if you were under my car taking the old ones out and putting the new ones in you would understand. old ones were just there, didnt really serve a purpose...the new ones had so much more pressure that once i finally did get them in my rear sat up just a little bit higher.

 

then your mounting area was rusted to shyt...I don't advocate using them.. I have a friend however that wanted me to put a set on after we fixed the saggin rear by a set of new springs.......and this is on a high 12 sec cougar.....they refuse to take them off and no damage to theis day..I however did cut the back off the car and repair all rust...which is why damage as such usually occure do to the age of the metal being weakened by rust over the years.

 

the floor had no rust in the rear it was mint this car pulled the front tires so it was no slouch either. but irregardless of the times the car ran mine was a dd for about 4 yrs so it was probably subjected to much more strain,but i dont know how he used it. the shock mount int he floor is nothing more than sheet metal its flimsy and cant support 1500lbs or so it has to give it hasnt happened yet but it will!! all my damage occured in one good bounce the entire tear was fresh shiny metal!

+1 on Scott's answers. If you tightened the springs too much while lifted, you can seriously effect ride height.

 

Scott is always very helpfull the upper shock mount on the early mustangs is thin metal and when you make it load bearing it gives out has nothing to do with rust. Most air shock boxes say only use on cars/trucks with a frame for that reason.
