UPDATED: Replacing Rear Shocks: Reducing the rear end bounce.

[azerik]

Oh my. Just found this thread.

I just purchased a 2023 GT and I wish I’d done more research. I test drove it extensively near the dealer but after one week I’m ready to take the hit and trade it in. I drove a leased Jag I-pace for three years, loved it, but was excited when I picked the Mach-e as my new vehicle.

If you think you have to get the ride close to the i-pace, trade it in.

That’s what’s it’s sounding like. I don’t need it to be the same as the Jag, just not like riding on a waverunner jet ski in choppy waters ?

Sounds like ,You, Like me, Didn't extensively road test the car on the roads that are causing you to think about instantly getting ride of it. I went through a couple weeks of anger with this car. Now I'm good with it and happy I have it. (The 400+ mile round trip I spent on this weekends drive was almost better than my RX450H. Gas VS a lot of hand free driving and no gas.)

Also sounds like you'll need to spend a bit of time going over this forum for your other options. Or scrap it and take the hit.

Your current options are:
Swap the shocks. *bouncy ride becomes firm sport ride (oh look you're already here and we've already done the footwork on this Page 1)
Rear sway bar *side to side sway control
Play with tire pressure *actually makes a significant difference. Too low and it bounces on baloons, too high and you feel every pebble.

Yes Ford under engineered the suspension in this car. The above are your options at this time.

I believe he has only had it a little while. Won’t be as bad when you get used to it and there are things that can make it better

answer doesn’t always have to be, trade it in. Might be the answer down the road. The car grows on you.

I am another that was quilty of not properly test driving the car, at least of the right roads.

rear Steeda helped, at least it I thought it did, while I had the car in Florida. Back here in NY roads are horrible and we didn’t even have a terrible winter.

I think the Steeda front and rear sway bars dramatically improve the handling and left/right stability of the car. But IMO, they don't do anything for the up/down bounce. For that issue, better shocks are needed. Of course over rough roads, the left/right stability improvement from the sway bars could really help. It just depends on the roads.

The bottom line: the government sucks. Otherwise, all our roads would be smooth and we would love how the MME rides. ?

I know about the side to side and up and down but a guy can dream

from steeda web site, (if every 2014 mustang shock fits, with adaption mentioned elsewhere), iwas thinking of these shocks.
Koni Mustang Special Active Rear Shock - Single (2005-2014)
Part Number: 279 8245 1405
MPN: 8245 1405

has anyone tried them?

The problem we still have, even with these is the ride height of the shock isn't engineered to the ride height of the MME. At ride height the piston sits in a sweet spot in the shock. It's usually got a little more give in order to soften minor imperfections. We have no idea where that piston is in relation to that sweet spot. As the piston in the stock shock is actually about 2 inches lower in the body than the Koni's for the 2014 Mustang I wouldn't bank on it adjusting correctly. It sounds to me like a multi floating tube shock. BUT that shock is designed for the weight of the rear of the 2014 Stang. We're substantially heavier.

The MME actually needs nearly no compression on the shock. I proved that out with the Vikings and that 0 or 1 clicks in provided more than enough compression dampening. With the Yellow Koni's we're slowing the rebound as much as we can. They have a good mix of compression, though it's not right in that sweet spot that these shocks were designed for. I'd be willing to put money on the fact that if I could extend the shock rod about 2 inches the ride would significantly soften the minor things better. The problem being, no one is going to feel very confident putting a small extension on the shock end. The thing the Vikings some with is the best example of what I'm talking about but the thread size won't work. And you couldn't get to the adjuster if you wanted to without having to take that extension back off. (the little black bolt bottom right)

Erik answered your question but as I have mentioned a few times before, the ONLY shock that you can use is one that has an adjustable rebound and the Koni shock you mentioned has no adjustability at all. There is no need to try any shock that is not adjustable as it will not help the bounce situation.

On koni web site, they are looking for volunteers near the Cincinnati area

This is great news. After 2+ years it is about time someone develop shocks for our cars and after all of my testing, Koni would be the one to do it beings they have rebound adjustability. I have messaged Koni at least 4 times over the past couple of years in hopes this would happen.

EDIT:
After searching this forum for members living in the Cincinnati area, I found ELEVEN and messaged all of them about Koni's request to test a Mach-E. I asked if they were willing to do this to let me know and how it went after Koni was done with their car.

Make sure they get a GT and a Premium car for testing.

I was thinking the same thing: they need a fully representative sample. (Seems Steeda didn’t quite do that with their sway bars… ?)
