More ways to soften the ride quality
After replacing the shocks with new a few years ago, there was a noticeable improvement. However potholes and other unevenness in the road still produce uncomfortable squeaks, bangs and rattles. That does reduce when I have driven at least an hour, so I assume by then all rubber components are nice and warm and soft. Or is it that the shocks have warmed up by then? Anything I can do other than going back to 16 inch wheels?

Aryan,
you could try running tyres with softer sidewalls or at less pressure. I have found ride on my 17" rims to be very sensitive to tyre pressure. Also the tyres before the ones I have now produced a smoother ride.

In the early years when the 16 inch "low profile"tires were state of the art for performance Porsche offered the 15 inch rims as a comfort option.....things have not changed. You need more rubber between the rim and the road. Solid rubber tires were invented first but then air filled tires became the norm 
As mentioned softer sidewalls help ride but also make it easier to bend a rim. Cheaper lower rated performance tires tend to have softer sidewalls.

Ok so you all agree it comes down to tires. Looks like you're saying it's a trade-off between slow speed comfort and high speed stability?
I have currently on Conti Sport Contact II, 225/40 and 285/30. I guess 40 and 30 sidewall height don't leave too much room to play with tire pressure, but can try.
So suspension bushings aren't a factor for comfort?
What I still am wondering about though, is how come the car feels much smoother after at least one hour driving?

lubrication, Koni FSD tech, and torque/replace
A brand new 928 back in the day would not do any of that just as any new Porsche shouldn't today. Sounds like worn out parts and even with high performance rubber, good shock tech like Koni FSD should just result in a solid dull thud. That is why a number of us here want them. (maybe we will get them someday)
The 997 S I drove had very large high perf tires and I drove it on lousy Boston streets and over a train track, no annoying sounds just the muted thud. Even with lesser shocks there should be no squeaks or rattles. I would like 90-S4 togive a detailed report on his cars ride as to all these factors, he has the most interesting suspension set-up here that I know of.

Hi Aryan,
Do you have 17" or 18" wheels?
If I compare the ride of my 928 to my 535d, the 928 is usually more comfortable than the BMW.
I have 17" on the 928 with the original shocks and springs.
What tire pressure are you using in the 928?
The advised pressure, especially for the rears is (too) high in my opinion, I drive it with 2.5 bars on all 4 corners.

In my experience my previous set of expensive ultra high performance (summer) tyres (Goodyears) were more comfortable than my current high performance (all season) tyres. I have no experience with the conti's. YMMV

285 / 30 / 18 in the rear is not a lot of side wall. Any increase / decrease in tire pressure makes a big difference with low profile tires. I have 275 / 35 / 18 on the rear with 235 / 40 / 18 on the front. I recently increased the tire pressures all around and she rides much rougher - You can feel EVERYTHING...
What tire pressure do ya'all recommend - front & back?
