Re the new crash testing. I was the "Technical Director Air Cushion restraints' for Allied the worlds largest manufacturer of "Seat belts' and at the time Air Bags. I can say with confidence that changes of the type we have been discussing would not require recertification or crash testing of the vehicle.
Second the release does have the wording changed coincidentally with lots of discussion here and other Genesis forums after the release. Hard to think of any reason to change it other that for many of the reasons we have been discussing.
Third. The vehicle height is established by the set extension of the Damper shock and the ability of the spring to support the load at that height. In other words the spring has to push the car up th the max stroke of the shock stop. This may but is not usually a elastic shock. Coil over kits usually have this set at less of a extension so as to lower the car. The actual spring itself can be a lower rate (softer) from that point on or higher to eliminate bottoming. Since there is only so much travel available from upper limit to bottoming out, the rate can only vary so much. It must have sufficient initial load at the installed height to hold the car to the stop to achieve the set height. From that point on the rate for the remaining compression stroke left must be at least limited by that stroke and the minimum being the initial load to a final load after the stroke is completed. It is likely possible that this change in load for the remaining stroke could be less than what we currently have.
The sway can be effected by the torsion rate of the anti-sway bar or the torsion bar or whatever you want to call it. It would have some impact on one side jolts but it is a trade off on tilt in curves vs transfer of load jolt to the other side.
So the main / real job of how hard our ride feels to small and or repeated small "jolts" is mainly left to the shock to establish the speed with which the suspension is allowed to move.
Therefor, one main way our ride can be made to feel easier / softer, etc. when it hits small changes in level by making it allow greater excursions per pound / inch /second that is led to a major extent by the shock.
IMO, All our cars need is different / softer dampers be they SACKs or whatever, to achieve a ride improved sufficiently to satisfy many of us..
There are other shocks that can be fitted to the rear of our cars and indeed different shock/damper assemblies for the front.
Should Hyundai make these for 2010 then we can get them if was are so inclined, With Hyundai hiding behind "Many of our customers are happy with the ride" my personal hopes are low. If Hyundai does not make new ones we can buy others if we want. I imagine we will ultimately find an acceptable new shock and in my case first for the rear and if that does not fix it enough then also for the front.
We can also sell our cars without fear as Hyundai says "many of our customers are happy with the ride" Personally I would try a 2010 and if the ride is great, see if Hyundai would give me a "Customer Loyalty" rate for the new car. I like the car otherwise and for the price I like it a lot it.
As I said before, enough said so I will try and not offer more un solicited comment, hope I can stick to my thought.. Please this is not an attack on anyone, any thought, any position. It is just to try and provide useful info from a Mechanical engineer that ran the Mechanical engineer department of the Bendix Research Labs. and we had a number of programs related to suspension. By the way this post is also not meant to boast, be self aggrandizing or talk down to anyone. Just trying to add some perspective and help while I try and cope with a very disappointing situation. I have to drive it every day as it is my only car so I have to try and do something to make it better as it is so tough to get in it and take the drive. Which is why I changed wheels, tires, etc. as waiting for the tooth fairy just doesn't do it for me. Thanks for reading this it took time to prepare and write it.
