Do you have wires coming out of the top of the shocks?

You can see them in this photo (White "L" shaped connectors in front of tower brace):




If you do, then you have the Magnetic Ride Control option F55/FE3, and based on your speed limited message you very likely have MRC.
You should be able to replace them with STS parts, I can't imagine the the small body stretch between STS and SLS would change the suspension at all.
So if you used these parts I'd fully expect your speed limiter would be removed.

No idea if Amazon will ship to Kuwait, but they seem to be about $400 USD right now each.

OEM REAR PASSENGER MRC:

OEM REAR DRIVER MRC:

Rear MRC is identical for AWD and RWD cars, front is different for AWD cars.


OEM FRONT AWD MRC:
ACDelco 580-437 https://www.amazon.com/dp/B00EDQ1SGC

OEM FRONT RWD MRC:
ACDelco 580-436 https://www.amazon.com/dp/B00EDQ2FR8


If you want to change to a passive system you'll need to install one 50 watt 3 ohm resistor at each shock absorber location to fake the computer into believing there is a MRC shock present.
Then you can install the standard passive shocks that the base model STS has.
