Eibach F/R Swaybar Review!

[mhal8876]

Good info guys!

 

[NoTyme]

Do you still feel the guys there in cary are the heat.. I just got springs and sways (eibach) that need to be installed. If you have any contact info that would be great on who did the work for you.
Thank you kindly..

I figure I should re-review my setup since I've gone through a few configurations. I highly recommend any of these combinations, huge difference over stock.

FYI I'm AWD, I don't expect that will change a review much for the RWD cars. I also have Whiteline endlinks.

Stage 1: Stock Springs, Rear Sway on soft:

This is great, and if nothing else this is a good starting point and gets rid of a lot of the vagueness present in the rear end of the car, as well as reduces the sloppy g-bumps many people (including myself) complain about.

Stage 2: Stock Springs, F/R Sways on Soft:

There was still a small amount of, while hard to notice, imbalance in roll between front and rear after the install of just the rear sway. The addition of the front sway left the car feeling much more consistent, and also drastically improves s-bend stability, and an improved response during turn in. I'd recommend this over Stage 1, but 1 was still a nice change.

Stage 3: Eibach Springs, F/R Sways on Soft:

I honestly feel like the Springs are a little too soft, but I expect many people will like the way it feels, it's very close to stock. Pretty much all of the roll is gone, and the car feels great around corners, there's a small amount of oversteer tendency set up like this, but this feels good to me (not at all the short wheel base snap oversteer of my Z, it's controllable, just don't tromp on it mid corner.

Stage 4: Eibach Springs, F/R Sways on firm:

I felt with the Springs that while the sways on soft with stock springs felt like a nice balance, with the stiffer springs the sways weren't quite keeping up.

I'm finally satisfied, I'd now classify the steering as sharp, the car is very pointy, changing directions quickly with steering input, rather than waiting for the roll and weight transfer before vectoring. Car is on rails.

I've only had it on firm for a day, I need to get on it a little more to review the balance but so far very happy.

Nice review, thanks for the comparative tests.
Do you plan on fitting the Whiteline HD Endlinks? I have Eibach F&R on softest settings with OE Springs & after a 6 months fitted the HD Endlinks & this addition took it to another level & completes the overall package & my handling requirements, I find the cornering balance of the car at higher speeds is much more planted & precise.

I have Whiteline endlinks front and rear, I did them with the bars, that's good feedback, I'm not sure what it feels like without them

That’s good, & btw mine is RWD (that’s all we get in AU) but I think we both agree this is how the car should have been out of the factory & it truely delivers this car as a proper GT.

Agree, at the very least, stock springs and front and rear sways, that's really all it took to not feel like a Buick.

UPDATE:

Sooo, not necro bumping, but I installed these sways on my '19 GTS, and it does not end up feeling the same...

On my '18 GT, the swaybars completely transformed the handling, and it felt like a car that was ready to tear up the curves.

On my '19 GTS, the swaybars feel like marginal improvement. It's as if the car can take turns faster, but that the limit is still about the same. I checked and re-checked the installation, even compared it to pictures of my old installation (some of the same ones in this thread), and everything is identical. From what I can feel, though, it's the front that is not as responsive as it was on the '18 GT. Case-in-point: I got minor understeer on a curved road I've taken on my old GT at the exact same speeds. And yet, as before, everything I'm looking at is nigh-identical visually...

I'm going to be purchasing the Whitelink front endlinks to see if I can adjust the length to then change the "response time" of the front swaybar through pre-load. Since the swaybar is free to rotate on the Eibachs, the pre-load is minimal, but the angle at which the bar is responding to different suspension load side-to-side changes. My hope is that will bring me "back" to the way it was on my '18 GT.

Is the 18 AWD or RWD? The extra front end weight and driven wheels would be enough to cause the more neutral behavior. What setting front and rear? Stiff or soft?

RWD. My '18 GT and '19 GTS, on paper, are very close in nature with the GTS getting an LSD, HK sound system, and a sunroof (along with the small safety options like the blindspot monitoring). This is why I'm so shocked that the more I dive into it, the more different the two cars feel.

 

[ghodge]

Does it feel any better driving in drift mode where all (or vast majority depending on which article you read) the power goes to the rear? Maybe it’s the extra 150 or so pounds hanging over the front.

 

[General_Vodka]

the power steering is calibrated differently between RWD and AWD. that would probably cause different "feel"

LOL... I said they're very close on paper and listed the differences: my '19 GTS is also a RWD.

So, AWD GTS? Less than 500 D-AWD were made. It would be a totally different animal from your MY18 GT. Why would it need to feel the same to satisfy you? Just adjust to the different handling feel of the different car. Nothing is wrong with it.

I literally cannot facepalm hard enough at your post, considering the one right above it.

Ah, it posted while I was writing mine.
So, there is effectively no difference in the equipment on the '18 and the '19. Both have LSD. Both had and have Eibach sway bars. But the new car understeers, annoyingly so.

Do you think something is wrong with the GTS? If there isn't anything wrong with it, I'd be ascribing the different feel to the differences that nobody can predict in two different vehicles. This happens even in slot cars, which are far more simple than 1:1 cars. You build two identical cars, as humanly alike as possible, and one handles better than the other.

If your new GTS doesn't feel "bad", just different than the GT, then get used to it; adjust.

No, it's objectively worse: understeer under the conditions of the curve I regularly drive indicates an imbalance. WHAT is causing it, I can't tell as so far, everything visually passes inspection. And no: these are not handbuilt; they will not exhibit humanly noticeable differences without actual differences, hahaha! They will exhibit different tolerances within the range which usually equates to some having more ticks or noises than others. But the feel of the vehicle will be the same because they're mostly built by machinery rather than human hands.

BUT, my '18 GT did NOT have an LSD (as mentioned above as one of the differences, come on man: read! lmao). While that only comes into play under certain conditions (and does affect handling, but I expected that), this is not one of them since the curve and the speed it can be taken at while maintaining constant throttle should not be engaging the LSD (our LSDs are mechanical). This isn't a "getting used to", it's a "certain maneuvers are more dangerous in this car than my old one", lmfao

Up there, somewhere. I scrolled and didn't see it immediately. Come on man, LINK! 'Tis a courtesy.

Yes, machinemade will have differences; the machines are manmade using other machines that are manmade using other machines and so it goes endlessly back to knapped flint tools.

No LSD on the GT means that your GTS is going to react different. That alone could be the source of the understeer. Do whatever works to induce oversteer. http://www.morpca.org/drivers-education-guide/understeer-oversteer/ Cheapest/quickest would be playing with tire pressure. More permanent would be to soften the front sway bar or stiffen the rear sway bar. Etc.

I'll rephrase what I'm saying just for you: my '19 GTS is objectively a worse car than my '18 GT, and I understand if these newer models overall aren't selling as well (or sales are declining), and that people with newer models are looking to move onto other vehicles sooner rather than later. The things I'm feeling translate to less logical means for other people and simply result in them finding other vehicles that feel better. The way my '18 GT behaved/felt was punching wayyyyyyy above its weight. My '19 GTS is just good value per dollar and a good looking car: it does not impress the same what with all the interior ticks and clicks, the heavier heave of taking corners, and so far being a little slower likely due to its increased weight. My efforts to mod to improve these things are not having nearly the impact it did on my first one.

Still a good car, but just good for the price. It's no longer the stellar car my first one was, and now I can understand why some people might be moving onto other cars. This is not because of machine tolerances, lmfao
