For the most part I agree with you. I had let my tires get too low as well and pumped them up to 35f and 36r cold, and they each raised a couple of psi when warm. I felt 36-38 psi was a little too stiff, and found I prefer 34-35 when warm, for a little more comfort. Or maybe it's the Potenzas also contributing to the stiffer ride. What tires are on your GS?
I've got Dunlops on the '18. I'm loving the added psi. Handling has literally been transformed and ride overall feels smoother because of how much less wallowing there is. I'm in such disbelief at how much more in control and planted the body of the car feels with the only change being tire pressure. I think I must've been stupidly low before. They were last set by the tire shop that fixed the nail I had in one of the tires. IIRC, they were 30 front 31 rear cold.
Our '15 has Bridgestones. Not sure if this is the contributing factor but assuming all else is equal between the '15 & '18, I'd say the '15 doesn't ride as smoothly as the '18.
I noticed the Kid's Castle in the background. My co-workers and I used to play ultimate and soccer at the nearby park. We actually have the same car color, Atomic Silver with black interior. I also did the carbon fiber trunk logo inserts about a year and a half ago. If you see an Atomic Silver with personalized Legacy plates around Burbank Empire Center area it's probably me. Also got my car from Keyes Lexus.
Photos to come but following are have/are being performed in the shop: Tinted windows, full chrome delete, dual dash cam, V1 install, SK front bumper lip (fully painted Obsidian), HID 6000k upgrade and Front LED Turn signal upgrade (completing all incandescent to LED upgrade all around)
I ordered one of those pumps off Amazon that you can plug into a 12V socket in the car. It also allows you to set the pressure that you want and then will automatically stop once it gets to that point. I set the tires to 35 front 36 rear as recommended in the door jam. The pump seems to fill exactly 1.0 psi above what you ask so I ended up with 36 front 37 rear and the car's readout confirmed this.
I'm still seeing the same handling improvements but the ride is noticeably smoother. Honestly feels pretty perfect and it makes sense... Lexus engineers want those tire specs for a reason, the car was designed to be run with those pressures and I'm sure all the various systems are calibrated for it so it makes sense to listen to their recommendation as closely as one can.

You're having the shop do ALL that? Most of the fun is installing the mods yourself! Other than the tint, I probably would have done the rest myself... so much fun!
Mind you, I'm not judging, I do understand that some owners don't care to spin the wrench themselves, it's all good, to each their own.
And don't forget to post pics when it's all done, perhaps even some progress pics. Us nosy folk are insatiable! LOL.
You guys getting all fancy. I have my $10 walmart air pump I've been using for 10+ years and one of these gauges. The digital ones are always off. I end up adjusting the tire pressure 3-4 times a year.

I have a lab-calibrated tire air pressure gauge, and I also have a few really cheap digital tire air pressure gauges (see below) I use. The cheap digital tire air pressure gauges I use are all the same Victor brand, and they are all accurate when comparing them to my lab-calibrated gauge. My Lexus TPMS readouts are within ~¼ psi of both the digital gauges and the lab-calibrated gauge.
If you want an excellent digital tire pressure gauge (with 0.5 psi readout) that is very accurate (at least mine are), yet costs less than $10, I highly recommend this one.
