If you have 19" rims consider getting 18's that in itself will make a big difference in ride quality with more meat on the tires, if your roads are that bad. I have an affordable set of 4 oem ones for $650 shipped in the marketplace that can be refinished in any color.

Base model 18 inch

Uncomfortable meaning too stiff? Floaty? Too much body roll?
If the shock is damaged replace them, next would be check tire pressure, tire/wheel size.

You're willing to ship to Saudi Arabia for $650?

I think the roads are what did it on the OP's car. 56k miles is too soon for bad struts on these cars. It sounds like you need new ones...and as others have suggested, perhaps go with smaller rims and beefier tires to help absorb the rough roads.

In that case, you need to replace your shocks and try to avoid all the potholes. Consider 17" rims that's the smallest rim that will fit, you would gain about a half inch of tire that will help protect your suspension and smooth the ride.

It may be worth noting that the GS isn't a floaty Lexus like the ES and LS. It's a firm sports sedan to compete with the Euros, I find it comfortable but roads here are rather good. Repair your car, sell it and buy an ES.

If your dampers are leaking - and you're after a comfortable ride - best replace them with OEM dampers.

The 2013-15 dampers may be firmer than your 2016-19 dampers, because the 2016-19 were deliberately made softer and quieter since the original 4GS was too firm and sporty.

The KYB aftermarket dampers are likely to be as stiff as your original, if not - even stiffer, because it is easy to firm up a suspension, but more dangerous to make a vehicle floatier, because this compromizes the handling.
There won't be too many aftermarket damper suppliers game enough to invest large sums of money into developing and testing softer dampers for your model.
Hence, rarely are aftermarket springs, dampers and roll bars softer than OEM components.





To obtain a more comfortable ride; from simplest/easiest, all the way to most complex/hardest:

1) Lower Pressures
Try lowering your tire pressures from the recommended 33 PSI [230 kPa] on the door sticker to just 32 PSI [220 kPa], but at this lower level, you will have to check your pressures at least once a month, otherwise uneven wear may occur.
If you're averaging highway speeds of 60 mph, better to stick to the recommended 33 PSI.


2) Tire Model
What is your make and model of tires?
The OEM Dunlop SP Sport Maxx 050's are sports tires with a soft compound, but stiff sidewalls to maximize handling.
The OEM Bridgestone Turanza T001's are touring tires with a soft ride, but they are very noisy.

Try switching to Pirelli Cinturato P7 A/S Plus 235/45R18 with both the same load and speed rating as the sticker on the inside of your door; the higher the load and speed rating, the more uncomfortable the ride.
The P7's are touring [sporting-luxury] tires have both a reasonably soft compound, and reasonably flexible side walls for superior ride and low noise.

In my experience, Michelin's Primacy touring tire series has a hard compound, but soft sidewalls - resulting in bumpier low speed ride and more tire noise.


3) Smaller Wheels & Tires
Because you have the base model, double check with your local mechanic if you really do have the smaller front brake discs and calipers for clearance so that you can use smaller 17" x 7.5" rims with a much more absorbent taller profile 235/50R17, or even 225/55R17 tires, and match that with the Pirelli Cinturato P7 touring tires mentioned above.


4) Softer Coil Springs & Dampers
I have test driven the 2017 GS300h in Paris. It has a beautiful ride; totally different from the US.
You can search overseas GS300h coil springs, or even overseas Japanese Domestic Market JDM 2012-18 Toyota Crowns which use the same platform on very soft compliant springs, but this is getting very complicated and tricky, because the GS300h has a lighter nose with a 2.5 L four cylinder....
