I run 32 psi cold at the track. It works out to be 44 psi hot. That's the only time I run less than recommended pressure.

So the 36 psi for US vehicles is consistent with this chart. There is no public road in the US where you can legally drive at or over 210 kph. From a practical standpoint, you would need to live near a road with no speed limit to actually need higher pressures. Under 210 kph covers the vast majority of driving no matter where you live.

What is the consensus with custom air suspension with electronic dampening? Would it give a ride quality nearly twice as good (its twice the price) as the KW V3's? My concern about the electronic dampening is how would the installer know what parameters to set the computer to? Cars that come with that sort of suspension setup had millions of dollars put into research and development to dial in all of the suspension calculations. I would also have to figure out if I would be ok with having a massive air compressor and computer in the trunk.
Going to be calling around more shops today and the dealer to price things out.

Got pricing from the dealer for 2014 ISF shocks and springs. It is half the price of the KW V3's installed. I think they include an alignment. Another wrench thrown into my decision...
EDIT:
After reading this:
"Sadly, while the driver is having fun, the passengers may not be so comfortable. Back on the road, and even at mediocre speeds the firm ride can leave those in the back feeling pummeled."
From the 2014 ISF slashgear review, I think they wont be that much of an upgrade.

I'm really not trying to be rude here, but if you're looking for a car that has a smooth ride, the ISF is probably not the car you should have purchased. The ISF is a sports sedan made for performance... And performance does not *usually* equate to a smooth ride, especially when comparing it to a Cadillac SUV. This is kind of like buying a Hell Cat and then trying to find ways to pull power out of it because you're not use to it.
The suspension suggestions on here are good and there are plenty of knowledgeable people on this forum, but there are no suspension upgrade options out there that are going to give you the ride quality (or anything close) to that of an Escalade.

I actually had a chance to test drive the new ES350, and it is Escalade smooth, if not smoother. The problem is I love every single aspect much better on the ISF, just need to figure out the suspension issue.

I would say the ride quality is comparable to my 335i w/Sport Package but when the road turns rough, the 335i crashes over imperfections while my '12 ISF soaks them way better. My ISF also rides much better than my old 2011 IS350 w/F-Sport "Catalog" Shocks/Springs/Sways.
Another comparo, I was driving my sister's 2013 Mercedes E350 just yesterday and thought to myself how much better my ISF rode than her car. True story. The ride was nice and firm but once you hit a small dip in the road, it almost feels like the absorbers just busted through the shock towers. Is this a German car trait or what?

You really need to take a ride in the back. It ain't pretty at all. AMHIK.
