Has anyone tried the KW V3 coilovers?

[Ty Davis]

1)Active damper system
2) My Stinger also bounces over bumps in corners.
I read most threads of the forum about the Stinger suspension and my guess is that my car settings are the same as the US version and the G70 is set very softly here for Korean people who expect more of a luxury vehicule than a sporty one from the Genesis brand.

Thanks for this information. That completely makes sense.
I really wish I could test drive all of the Stinger/G70 variants around the world, to see how they are tuned.

You have Neotech in Korea, I would visit them. Their coilovers are excellent and feature an NVH upper mount.

I saw your review of the Neotechs in other threads. You mentioned they were great, but really didn’t Go into detail about them. Would you mind elaborating a bit?

Do these coil overs ride flatly or do they bounce at times?
If they bounce, is the bouncing at the front, rear, or both?
Do they make any noise? Do they ever get harsh? The stock suspension allows the body (car) to rock back and forth slightly for a bit after each stop. (It’s not quite brake dive, but the car rocking on its tires or suspension bushings) Is this eliminated with the Neotechs?

Does the ride quality ever get jittery? What does the Neotech suspension do BETTER than the stock suspension? More importantly, what does it do WORSE? How is the ride at low speeds on less than perfect roads?
Do the higher spring rates make the car sound boomy, thumps, or crashy or bumps?

If you could answer these questions and provide any other input you may have, I would greatly appreciate it.

Thanks a million!

I had KW coilovers on my G37 sedan for about a year and they were really good. They are a quality product, just don't know how the tuning is for a Stinger...

 

[Never thought]

To go a little off topic, I love the Eibach springs. It took away probably 90% of the bounce, handling is much improved as body roll has greatly decreased AND the ride has improved as it’s not nearly as harsh over road imperfections. If you are looking at a solid cost option, Eibach springs are fantastic.

Only time will tell....

Does KW do a height adjustable spring (HAS) kit for the Stinger? I had those on my Audi A5 and liked them. They allow you to maintain the electronic damping of the stock shocks and provide ride height adjustability like a coil over.

It’s a threaded collar that slides over the shocks to provide adjustability and then a replacement spring.

This is great! I wrote to them back in March of 18 asking them to consider coilovers for Stinger. KW makes very good quality coilovers. Have used them on my Porsche’s. They use Koni tubes for many of their coilovers.

I don’t think they do. At least not right now.
Is this really the solution you want for the Stinger though?
Sure, HAS would allow you to change the ride height, but they do nothing for the Stingers insufficient strut/shock valving. Might as well just get lowering springs instead of settling for the HAS.

I do understand that the HAS offer more adjustability of ride height than springs. I also understand your desire to maintain the electronic adaptability that the stock suspension offers. Be aware though, that the difference between modes on ECS is rather subtle. Ride quality is nearly indistinguishable between Sport and Comfort. What you do get is a bit firmer body control (not firm enough though) in Sport mode.

This EDC system is not worth avoiding other products to keep it active.
A properly designed aftermarket solution will have no problem out riding/handling/stancing the OEM EDC system.

HAS are great for a car that already has good suspension valving and calibration. But the Stinger “needs” more than just ride height adjustments, unless your are ok with bouncy OEM suspension...

If somehow we could gain access to the stock system tuning and are able to get it tuned like the Genesis G70, that I feel would work for most. I’m pretty sure it uses the same system since the cars are built on the same platform. The tuning is different to make them feel the wway they do, GT for Stinger, Sporty for G70.

All valid points. My Audi had a much greater range of damping than the Stinger so the HAS kit was a perfect solution.

I already went with the Eibach pro springs and am happy with them. Not everyone is prepared to invest upwards of $2,000 for an adjustable suspension. A HAS kit provides adjustability for a fraction of the cost of a coil over kit for those who don’t want a static drop from a lowering spring alone.

I’d like to see an aftermarket tuner or even Hyundai/Kia offer various “tunes” for the Electonic Damper System.
Would be nice if they offered it for the Electronic Power Steering System too. If done correctly, they could charge a quite a bit for it and people would still buy it.

I’ve found that the Stinger suspension computer does not have the G70 program stored on it.
Each vehicle has its own computer for that system. We could possibly swap a G70 computer into a Stinger, but the results would probably be less than optimal. The G70 has a different wheelbase, spring rate, and compression/rebound valving on the shocks. The suspension computer only varies/controls rebound damping, so all of the other parameters would probably be mismatched for a harmonic ride, if a G70 computer were swapped in. To use the G70 suspension computer, it would be best to use at least the electronics shocks from the G70 too. For that expense, coilovers or lowering springs may be a better deal and result.

I’m gonna have to get some seat time in a G70 to see just how good it is...

 

[Waynerm002]

Wait, you have access to the info on the Stinger's computer? I'm curious to know how that looks and see if that is something that once can find adjustments to change for the shocks.

 

[brancky3]

That would be awesome if we could enable Sport+ mode which I think has a firmer setting on the suspension?

Yes. I have looked around inside the Stingers Electronic Controlled Suspension Computer and the Electronic Power Steering Settings too.

All of the global Stinger programs are stored in ECS computer. This means every Stinger is equipped, with the same software all around the world.
What makes different markets and trim levels perform differently is “variant coding”. Variant coding, tells the computer which of its stored tuning maps to use for your particular vehicle.

The ECS has several options.
1. Engine Type - 2.0T, 2.2D, or 3.3T
2. Drive Type - 2WD, or 4WD
3. Country Code - North America, Korea, Europe, Russia, or Australia

You select the combo you want to use and then code it to the car. Then your car uses that particular program.

Easy as pie... EXCEPT, none of the scan tools I have found properly code the stinger, and always result in a “Communication Error.”
My first scanner was an Autel Ms808. I can see all of the options but any coding failed. I sent that back and got a G Scan2. It does the same thing... communication error. I was hopeful that the G scan2 would work, because it is a product of git.auto (the manufacturer of the Kia/Hyundai OEM dealer service scan tool).

Anyway. I’ll keep working on it. Eventually an new update to the scan tools will come along that will enable them to fully communicate with the Stingers new systems.

I am pretty sure the Kia dealer could change the settings too, if the could be persuaded to do so.

But yeah, all of the settings are right there.

 

[Ty Davis]

This is what it looks like inside of the Electronic Power Steering menu.

 

[Ty Davis]

I’ll look for it tomorrow.
I doubt it is a stand alone selection though. It will probably require coding whatever module it resides in completely to another spec. That can be problematic, considering right hand drive, left hand drive, mph, and km/h, and other options could all be changed too...

I don’t think the drive mode selector has its own computer.
It’s probably with the instrument cluster module or the integrated control module.

 

[Waynerm002]

Nice! I figure the dealers could do this change but they likely won’t. It would be useful if there was a few more settings in there that would allow for tuning the damping rate of the shocks, to allow for a different setting than what it is now. Would be good to be able to change the settings for different countries and see how they feel or mix them up a bit. Thanks for the info on this! Hoping you can find some way to make some changes with this.

The Setting for Australia interests me most at this point... Aussie reviewers report that the ride is controlled in comfort mode and very firm in Sport mode. Several Australians have commented that Sport mode is so stiff that it is best reserved for the track. They do have stiffer springs and anti roll bars too, but still the additional shock valving would be nice to try.

I’ll find a scan tool that can enable this sooner or later...

The dealerships have been altering Sonata EPS settings for a while, according to the Sonata/Optima forums.
This is the same thing, but for the ECS. I will definitely keep everyone posted on my progress with this.
