best suspension for 5.0 mustang

well, this is an interesting problem. Interesting because stock suspension on a stock 79 shouldn't feel "rough". Sloppy? Yes. But not "rough". I'd almost think that maybe something is broken back there. You need to jack it up, remove the wheels, and inspect all of the control arms, bushings, torque boxes, etc. The most likely culprit is a destroyed stock bushing.

Of course, I'd recommend UPR Products suspension front & rear with Strange 10-way adjustable shocks and struts to tighten things up. The parts aren't too expensive, but they'd be a day and night improvement.

To answer your other questions, I don't think the 79s came with quad shocks or sway bars in the back. I think the GTs did have some weird looking slapper bar type deals on them though.

well everything under the car is from an 88 gt and i know it does not have the sway bar but it is all set up for it i just havent bought it yet and its not really rough going down the highway or anything just in town and i hit some bumps i almost fly out of my seat cause is so rough. Do you thing that lowering springs and struts and shocks would help this????

i dont believe it has lowering springs on it cause if you look at the pictures itt sits kinda high but with the suspention being from an 88 gt and a guy doing it i dont really know what he has done to it but i would llike it to sit a little lower so what would you reccomend for loweing springs??

spdjnky's right that usually the cars that ride rough are the cars that are too low. But who knows. Your question was "what would you recommend for lowering springs" so my answer is these Eibach springs from UPR: 1979-2004 Ford Mustang V8 UPR Pro Series Lowering Springs by Eibach at UPR Products - Lifetime Warranty!

That said, on a 79-88 hybrid Fox, you need to inspect all of the suspension for wear and tear. If a part is worn out, it can certainly make the car handle poorly.
