Hi everyone....I'm a new member. Does anyone know why my 1990 gt driver's rear sag? I have changed the suspension (BBK springs, Monroe Formula gt shocks and struts, sway bar and rack bushings) and still it leans. A reputable body shop says that the body is not torqued. The car has been parked for about six years now and I am thinking about redoing some stuff and putting it back on the road. Would like to fix the suspension same time. THX!!

If you have changed the springs and you STILL have the same issue, something is likely bent Just go through the likely things... do you have isolators installed and are all the same condition/thickness to be equal on each side?

Silly question, does the car have the exact same size tire on each side? This can sometimes get missed and what appears to be sagging is a 40 series tire on one side, while a 45 series is on the other.

Thx for the replies guys. Yes the springs are correctly oriented, isolators and tires are okay. The car was never abused or raced. Bought it new and the sag started developing about two years later. Progressively got worse over the years. Looking foward to more ideas. THX!

I misunderstood here, I think...

The sagging now AFTER you installed the springs reciently? This is not making sense to me, sorry At what point did you replace the springs and was this AFTER you noticed the sag.

Jazzer confused

Sorry if I was not clear. I changed out the suspension because of the original suspension was sagging on the driver's side rear. After the changeout still sagging.

OK... something is bent

You are gonna have to look more closely, as this can be the only reasonable conclusion. If the sagging is the EXACT same percentage with brand new springs, I would guess you have a bent control arm or shot bushings.

Keep looking
