Installed Mach-E Rally Springs on my 2023 RWD ER

[voxel]

Ride comfort: I immediately noticed that the ride is definitely softer than before. There is a street near me that has extremely uneven pavement, and whenever I drove on it I was constantly being jostled around. I drove on that road again, and I noticed a huge difference. I no longer feel any of the small bumps and imperfections on the road. Any larger bumps/imperfections were significantly duller and less bothersome. I no longer felt like I was being jostled left to right over the uneven surface. I also drove over some speed bumps. I used to be unable to drive over them at any speed greater than 20mph, because the rear always felt like it was slamming back down. This always knocked the cargo floor off the top position. Now I am able to comfortably able to go over them at speeds ranging from 20-30mph without that sensation. Honestly it feels pretty close to my wife's RAV4 in terms of ride comfort over uneven surfaces. Truly feels like a different car.

I just returned from two days at Electrify Expo Orlando where I test drove various EVs including the new Rally over surfaces with constantly minor undulations and the Rally has a hugely improved suspension compared to the bouncy mess in my 22. Almost as good as the the Volvo EX90 with air suspension and better than the new/improved Model Y.

I will even say the suspension should be better than the RAV4. I test drove a Lexus 450h+ (PHEV) that's the luxury version of the RAV4 Prime (I owned a 21) and that was pretty unsettled compared to the Rally MME.

I should try driving a Rally sometime. My wife's RAV4 eats up all the road imperfections whenever we are in Houston or Dallas which a huge step up compared to my stock MME.

I did so because I wanted the lowest drop, as well as progressive springs front and rear. The -03 kit has linear rear springs with the lowest drop progressive front springs. The -04 kit has the progressive rear springs with about the lowest drop. So I combined them and had to use spacers to get the ride height back up closer to normal. Not an easy task, but I'll see how it rides soon.

how many spacers did you end up using?

Thanks for this info!
As a man with 10 thumbs that barely can wake up without hurting himself in the morning; is this something one can ask dealers to do? Since it is Ford Parts it should not be too much of a hassle for them to order the right things, or? If so; Is it a big job (how much work time)?

I would order it directly from fordpartspros.com. They offered a pretty big discount compared to to the dealership. I found a local reputable suspension shop to do it for me.

It SHOULD be a job they can do but most Ford dealers don't like installing parts on a car that originally did not come with them because they believe it would void the warranty. In this case, that is not true but just don't think you will find a dealer that will be willing to do the job. Like giwu42 above, I would find a reputable suspension shop or any good car mechanic and have them do it. It is not a difficult process. I have done at least 7 Mach-E's here at my home but then I do have a lift and some of the special tools required for the job. Takes me about 3-4 hours for the entire thing.

It's sort of a guessing game with spacers. But here is what I figured out for the rear.
There is about an 85% ratio of spacer to amount you want to raise the rear. So if you want to raise the rear by about 0.6", then you need 0.6" x 0.85 = 0.51" spacer. I wouldn't add more than about 0.7" of spacer because there is a centering cone on the body for the spring and much more will risk shortening that needed cone.

I also added a thin rubber "washer" (cut from a 1/32 " sheet) to act as a sound damper between the spacer and the car body. It helps cut down on noise transfer.

Edit: The best diameters for the spacer are: 2.8" ID x 4.8" OD. I know Steda has a bunch of different spring spacers, but I don't know if they provide diameters. I machined my own in my shop.

Note:
The Steeda rear spring spacers work well on the Mach-E. Have used them on several of my cars (and others) to get the height I wanted after installing multiple sets of springs.

Mark, Does Steeda have any specifically for Mach-e, or did you choose spacers for a Mustang? I tried some for the Mustang and found they were a bit large (especially ID), but they did work as long as you make sure they are well centered before compressing the spring with the lower arm.

They are ones for the ICE Mustang just like the ones you tried. They are slightly larger but still fit well and there are several Mach-E’s with these spacers I’ve installed that have over 40K miles with no issues so they work well.

I wanted to follow up on my ride results after my "mixed spring" install (Front springs from Eibach -03 kit, and Rear springs from -04 kit, and spacers front and back to restore near stock ride height). With Koni's set to +1.5 turns (down from +2) and tire pressures set to 37psi cold - it feels GREAT! A note about tire pressure; I used to have my tires set to 41psi cold. With the spring change and that tire pressure - the ride was not impressive. Bumps and road irregularities still had a sharp initial hit. I lowed the pressures to 37psi cold - and now all road irregularities have a nice "rounded off" feeling. I no longer focus on the road surface and try to steer around things. I can just ride over them and it's okay. Very happy with the change. Rally springs were on my mind too, but I'm happy enough with my setup that I'll stick with it. I'm sure your Rally springs feel great too!

I would imagine now that Telsa has fixed the suspension of the 2025 Model Y; ford will pay closer attention to it. I'm an OG 2021 and love my car but have said since the beginning the suspension is too stiff!

Maybe a group purchase for those intetested

You can actually figure it out with math. Measure the whole length of the control arm to which the sprung is attached from its frame pivot point to the center of its ball joint. Call this A. Then measure the length of the control arm from its frame pivot point to the middle point of the spring pan. Call this B. The amount you want to lift the car is L. The spacer thickness is S. ??

So, S = L * B/A. ??

This gets a little hard to measure given 3-point control arms (aka A-Arms) because you have to use an imaginary point as the frame pivot point defined by the intersection of the line between the fore and aft control arm pivots and the line between the ball joint and the center of the control arm spring pan. Easier with 3D modeling, but doable with common measuring tools if you are careful. ??

How much and what city are they in?
