80mph + feels really floaty still

[Steve8989]

Had a barrel bent rim back passenger, replaced it by Ford to a brand new one. They only charged me 25$ for the tire swap to the new rim. [ paid for the rim ]. I thought that would of solved the float before but for some reason it's still there. Could ford of not done an alignment and or balance for the new rim ?

Do Bilstein B6 shocks and struts. Thank later.

As IPOGT said, shocks and struts are a good start...but, if you want a rock solid car you will need to go quite a bit farther, I had the same issue with my Bullitt which was a PP1 car and got "floaty" around 90 to 100, controllable but uncomfortable to drive, coming from a C5 Z06 I found this to be unacceptable, so I went full Steeda from front to back now the car is stable and comfortable to drive up into the 140s so far...not that I do that regularly, but we do see triple digits often as I drive on 2 lane roads where a lot and passing often involves a quick dump into 3rd for a burst around an 18 wheeler...

The problem isn't the wheel. It's a combination of both suspension and aero.

Suspension will take care of a lot of the problem but then you'll really notice other characteristics. Specifically hood wobble.

What tires are you running?

Mustang suspension tends to be really soft and floaty in stock form, unless you go to the performance models. The regular GT is set up as a comfortable Grand Tourer. It's not really meant for any kind of performance driving.

Stiffer springs and shock upgrade would be my solution, but then again I prefer a firm ride. If you want a soft ride you will probably have to live with some float. I went to the Ford Performance track handling kit on my car, because I wanted to be sure all the components were matched to each other, and I don't trust my patience to do adequate research to get it right. I think the FP track handling kit is just about right for street driving. It's a little soft for the track in my opinion, but that seems to be how Ford does things.

My LT1 Camaro feels generally similar in firmness to the FP track handling kit, and bumps or other irregularities in the road seem to send more vibrations through the Camaro (I think this means the shocks are somewhat stiffer, but the springs are similar).

What tires and what does 'floaty' mean? (what speeds, what road condition, and what driver inputs when its feeling floaty?)

When my car (GT w/PP1) was floaty, it was highway speeds and medium highway undulations , it would feel like it was kinda off the ground when going over bumps at speed. Better (stiffer) aftermarket shocks fixed that.

If your 2016 has never had shocks replaced, well, shocks wear out after 60-80k miles or so, and your GT-CS started with soft springs and shocks which feel floaty to some. This many miles/years later and the shocks are probably entirely worn out. Time to replace them, and try the Bilsteins or Ford Performance ones. While you're in there you have the option to do springs at the same time. Its the same effort on the front and a little more effort on the rear to replace springs too. Stock (modern) springs don't really wear out, but aftermarket stiffer springs are pretty cheap, but you'll pay a bit more for the install. Worth considering anyway.

I'm betting your alignment is off
No modern car should feel floaty at 80 mph lol.

Highly likely but many people even myself have noticed this in stock trim.

As others have said, it’s a Grand Touring car, not a dedicated sports car

My 2020 non-PP bone stock GT convertible feels perfectly capable in the low 100 mph range, top down. Zero float or anything that would be considered bad manners. And this is with the dreaded P Zeros which most here would tell you need to be shitcanned before you pull out to your mailbox. I do keep them at 36-37 PSI. No, it’s not a dedicated sports car but it’s a very capable Grand Tourer as correctly said in the post I quoted above. To say it’s not meant “for any kind of performance driving” is ridiculous. It should easily do what you want without taking a deep breath. My wife’s Outback will do better than that.

Something isn’t right; you just have to figure out what it is.

Maybe my frame of reference differs from most as this is my usual activity in this car lol

Well, um, yes I’ll admit that’s a little past my frame of reference for sure. Not counting what’s in my mind!

It's good that you posted this. I feel differently, but it's good to point out that people have very different standards as far as ride and handling goes.

When I purchased my 2017 PP1, stock it felt to me like an old school Cadillac. Way too soft, boaty and floating all over (body motions are excessive IMO and not controlled by the springs and shocks). I felt like if I accelerated in a turn the front tires were unloaded too much causing excessive understeer. And when I braked the nose seemed to dive way too much causing the rear tires to be unloaded.

Now, you have to consider that immediately before the PP1, I owned a 2004 Z06. And before that a 2016 GT350. The Z06 has a very soft and compliant ride, but it weighs 600 lbs less than an S550 and has a significantly lower CoG. Body motions are small in that car. The GT350 has a relatively firm ride and body motions are well controlled. I also owned a Fiesta ST as my daily/winter car, and it had a much stiffer ride than the GT350.

So my frame of reference is coming from much sportier cars that are built for good handling (comparitively). The GR86 I owned and my current Camaro LT1 also have much stiffer suspension than my PP1 Mustang GT did.

I installed the ford track pack on my 22 gt and it feels like it's on rails now.

About 5 years back I did the unthinkable according to some on M6G.
I paired Ford Performance track struts and shocks to Steeda Ultralite Liner springs.
The results, it transformed my GTPP from a spongy powderpuff to almost a real muscle car.
I’ve never looked back to date. Only other big improvement was ditching that stupid bonded front swaybar.
