Performance Pack suspension bouncy?

[Rv-Junke]

LMAO:lol:

You bet, always glad to help out.

I will also make this statement. Since the Steeda stuff has been on my car for almost 3 weeks, I have not noticed any bouncy rides at all. Maybe folks are less sensitive to these things or not but that is what I a feeling

NEWS FLASH....The dead body (AKA 175lbs) Worked like a champ, except the Hex Dumbells slamming around! In all earnest 100% improvement, except the extra weight you could feel as well as it made the ass end sway side to side.

I'm convinced, the engineers goofed on this suspension configuration. It feels like you have pointed out some parts are stiff, some are soft, but none are working together. I'm going to battle with Ford on this. Now that I got dead bodies in the trunk, I might as well get my Italian up.

I wish someone would come out with some coilovers.

So does anyone offer progressive rate springs tbat don't lower the car? I'm guessing not.

170 Lb's in the trunk! Works great....ARGH...so frustrating being told by Ford "...acting normal"

All GT mustangs are stiff. Been that way for a long time. They are designed this way. If you want soft then buy a Hundi or Kia. It will corner like crap but at least you are riding on your cloud. Pick your poison.

Not sure who this is too, but I think most of us especially those that have SEVERAL muscle cars and other cars know the difference between Soft, Stiff, and Bouncy. The 2015 GT PP, is BOUNCY, its stiff but Soft, so its a confused suspension. But yes you are correct Stiff suspension equals good handling. Soft is like riding on a cloud.

The 2015 GT PP, is BOUNCY

This is true as stated by many owners.

Watch the NASCAR cars go around the track. They get the shit beat out of them due to the bounce. They handle great though. A hard tail Harley will beat the shit of you as well and will throw you off the road.

I had a non PP 15 GT premium and now have a PP GT premium and the ride is definitely stiffer/bouncier in the PP car. I drove my non PP three hours over mixed roads to the dealership, got the PP GT, and took the same exact route home. Definitely a noticeable difference to me.

Several have now stated that the PP is MUCH bouncier than the Regular...I will be driving with the 170lbs in the trunk till I figure what to do, or fight with Ford till it gets fixed, or both!

Todd15 really explains the problem, it seems the Springs are STIFF and the Dampers / shocks are stiff but not for the 1st piece of the Spring so they fight each other. Thus compressing the spring to allow damper and spring to work in concert. MANY have said the Steeda Progressive spring helps.

It would be interesting to hear back from the Steeda linear spring owners and see if the bouncy ride is eliminated with those like the progressive.

I've recently purchased the Steeda progressive spring kit. I really had no desire to lower my EB, but I'm willing to do so if these springs will stop the bounciness. My initial plan is to install the rear springs only. Why?

- 90% of the bounce seems to come from the rear
- The rear springs are easier to install than the fronts

IF the Steeda progressive rear springs remove the bounce then I'll definitely install the front progressives as well. I realize the Steeda springs are a 'set' and work as a package, so if they work I'll obviously install the fronts so the 'set' works together as well keeping the drop equal front to back.

If not, then I'll remove the rear progressives and find a set of non-PP springs. Until then, I'll just keep a dead hooker in the trunk.... ;)

Yes I am VERY Interested...and as you can see I am not going to let this issue die...

Based on all that have done this, I am fairly sure the progressive will really help.

I am quite confused after reading through this thread, I have the linear steeda sportlite springs, they are now settled and the car is aligned within factory tolerances, My bounciness is gone and my spring rates are obviously higher than the performance pack GT springs that were in the car originally. I plan on doing different shocks and struts when they come out probably next summer, but my car seems like its much more planted and the bounciness is essentially gone, but based on this information lowering the spring rates would get rid of it not raising it.

One thing i did notice, going over a quick, drastic slope increase in the road (roller coaster hump effect), you to get thrown up off of your chair sometimes depending on the speed (the car does great the the seat belt doesnt hold you down).
