Eibach GT performance springs on a 4xer

[markboris]

Eibach Order Update: Your order #937905 has been shipped! Mine should be here Monday. I may shoot for doing my install on Wed

@Mark - Just wondering if your description of the bounce and the the left to right bobbing up and down is more prevalent to certain trims? I'm shooting for the Eibachs to soften the ride a tad more and hopefully eliminate the rocking horse effect that I get in my GT or what I believe Erik describes as front-end Pogo'ing. Are you saying that is only possible with the Koni Shocks?
Just wondering if different trim levels exhibit different things. Some are worse than others.

Hey Brian, I think you may have the wrong "Mark" in your post. ?

As far as the way the car rides in all the trims, they are basically the same except the GTPE. The PE having the MagneRide suspension rides smoother and have less rear end bounce than any other trim. The Eibach GT Pro-Kit Progressive Lowering springs will give every model trim a smoother ride. It is not night and day but it is very noticeable driving over all road imperfections. The ride is a bit more supple/softer. So far, these Eibach springs I've installed in a Premium, GT and GTPE, every member is enjoying a less harsh ride.

The Koni shocks that I modified to fit the rear of the Mach-E are strictly to be used for cars that exhibit the dramatic rear end bounce that one might get over particular roads (e.g. freeways with expansion joints, etc).

The sway bars will control the left to right pitching and also keep the car much more flat in the corners. So all three suspension components do three different things. Springs = softer ride, Koni rear shocks = reduce rear end bounce, Sway Bars = reduce left to right pitching and flatten the car in corners (better handling). Unless you have roads that induce the dramatic rear end bounce, I would not install the Koni rear shocks as they will bring back some of the harsh ride the Eibach springs are removing. There have been several members that have done all three suspension changes and are very happy with that setup also.

Thanks Mark. So when you say the Eibach GT springs are not Night and Day. Is that comparing them to the MME-PE? Maybe Erik's opinion of them was more optimistic when he said "Now I'd say it's as nice or better than the GTPE's I've previously driven" and " If I was to try to equate the tried I’d say it’s very similar to a GTPE in whisper ".

Unless I took that out of context. I also realize Erik has Koni and Swaybars as well so maybe those other components are helping with it being more towards the Night and Day differences. .

My opinion of these springs without shocks or bars is that it's very similar to the GTPE in whisper mode. It's not a jarring ride. It's also not firmly planted. The backend due to it's weight just kinda sways around a bit on wavy bumpy roads. (I have a premium but essentially now the GT's suspension/wheels/tires) I've dialed the Koni's all the way down in order to try to get an idea of what it'd ride like with stock shocks. Reality is the stock shocks have very little dampening at all. The Koni's only adjust the rebound side of it so even all off it's got a bit more compression dampening than stock. But it's not a night and day difference.

At speeds over 10 mph the Eibach's do great to turn road issues into something you notice but are not begging for it to be over as soon as possible. It allows the suspension to move rather than launching the right front tire 2 inches higher (throwing you to the left in your seat) then bouncing back down tossing you side to side, then doing it again with the rear wheel and tossing you side to side. You'd feel this in your ribs/shoulders. Bars help with this, they isolate that tires movement and keep the rest of the car very level.

The see-saw movement is more when you hit something square, like an expansion joint or hard dip. The car feels like it see-saw's front to rear. It's really mostly the rear. You feel this in your neck, front to back and your neck may well get annoyed by this depending on how many of these dips you hit. In my 8 mile round trip I have probably 40 of these dips/expansion joints. If I hit them while turning the car gets tossed left to right as well as all I can picture is a mechanical bull. (bars/shocks/springs resolved this unless it's just a super terrible intersection. Realize our stretts literally melt here 6 months out of the year and are repaired via duct tape and tar from the looks of it) Springs alone will help with the majority of these dips. I still have some that make it feel like you could be airborne, but every other car I'm looking at is doing the same or worse. I think Eibach did a great job with the spring transition for these. I usually get 2 cycles when hitting something like that, I used to get 5 or more cycles where the back is just continuing to go up and down after hitting the dip.

The front end pogo is very obvious at night. While driving the headlight just jump several feet up and swiftly back down. This is due to the stock spring rate being unforgiving, every little crack or imperfection is felt/seen. Eibach shaved nearly 50 lbs of (25%) of the initial spring force off the front springs and 200lbs off the rear. Allowing the wheel/tire to actually move and the shock to actually dampen that travel. I'd say a lot maybe 80%+ of the headlight bounce is removed to the point I hardly notice it. (and I kid you not I am constantly noticing all these things).

I agree with Mark in that these arn't going to change your car into something else as in night and day, because it's still a 5000lb bull in a China shop in heels. But it's a much more well behaved bull wearing Vans with the springs. The condition of your roads makes a big difference really. Mine are utter garbage. I also have anywhere between just myself to 4 adults in the car on these garbage roads. I was in a buddies Tundra on these roads and it was terrible. Happy to say my MME is riding much nicer than his truck, or my other bosses (not my wife) Mini Cooper.

Thanks Erik!. This pogo issue above is my exact gripe with the stock GT springs!.

I was quoted $925 of labor to install the four GT lowering springs on my regular GT.

• $460 for the fronts (including the necessary disassembly of suspension and struts)
• $290 for the rears
• $175 for alignment

Does that sound reasonable? Or am I being taken to the cleaners?

Hi phil, curious if you end up find a cheaper dealer, and what area are you from? I got quoted almost $1k to do both springs and sway bars in SoCal.

Hello Calvin - I got a quote of $475 for installation of the springs, no alignment. Same region, but not near Pasadena. I followed and agree with the advice given above to get multiple quotes. I am lazy, so I only got two, but the difference was big. Good luck,

 

[markboris]

With Eibach being in SoCal, maybe they know of some reputable shops that can also install their springs and sway bars?

That's a good idea. Of course, SCAL is a big place and Eibach in Corona is pretty far from Pasadena and most of civilization...

I’ve actually called before and at least their sales team says they can recommend as the manufacturer on which dealer to go to.

i got a new quote last night from one of their dealers for $880 on labor. They did break out spring installation alone at $480.

The bars are cake if they're already in there for the springs.

Ordered my Eibach sway bars this morning. Springs arrive tomorrow. ??

Hey guys how much was the camber off on your alignments? Just wondering if the adjustable camber bolts are recommended of if the alignment is only off slightly that won't really cause an issue.

 

[azerik]

The rears will only get to about -1.9'ish (right at max spec). It's bolt limited. So far we havn't found an offset bolt that would work. A smaller bolt possibly or some grinding. None of which I'll probably get to until November due to it breaking 100 here.
The fronts will go back together and should come up about -.5. I added camber bolts and pushed it to -1.5. I'm looking to try to get back to -5'ish all around ideally. We have a good amount of grooved concrete around here lately. MarK has alinement sheets posted as well in a couple places.

-5? Wow. I’ve set up race cars with less. ??

-0.5 sorry
