All alignment shops will know the factory spec range. I just ask them to set it as close as possible to the middle of the range for each side so that it's balanced left to right. Many people here have posted alignment sheets if you want to know the numbers.
Alright I will post my before and after alignment tomorrow hopefully and see what’s up thanks for the help
Currently at pops shop setting the car up for alignment, being super confused and not knowing anything about this stuff I’ll drop a picture of what my alignment looks like now.
If anyone can give me some recommendations to do something aside from just alignment based on the readings please let me know!! Before alignment specs Da whip on the rack lol
Alignment done, so far driving feels better 100% unfortunately it’s raining today so I can’t really push the car to its limits.
below, I will attach the alignment numbers after we got done with it. Let me know what you guys think.

This looks like the rear alignment and toe is way off. At least camber looks good. No new recommendations. Your alignment target numbers are not based on current numbers.

Yup toe was very bad.
What do you mean by my target numbers are not based on current numbers?
Also wanted to say that I checked the air on the tires again and it was all at 34psi… I was using the jacked up air gauge when I initially filled up my tires. They are now at 36psi
Yup toe was very bad.

You mentioned performing alignment based on the readings. What I meant to say was that your starting numbers are irrelevant. Maybe I misunderstood you. Looks really good now. Hope this resolves your stability issues.

Oh I think I misunderstood you actually haha
Thank you and everyone els so much for all the help you guys rock!!
I will give it a good test tomorrow when it’s nice and dry!
I’ve noticed that once a year, need to get alignment done. Around every 15-20k miles. And when the alignment goes “out of whack,” the car handles very poorly, like what the original poster experienced. The alignment shop is not the typical Firestone, but a racing shop that specialized in alignments, and every time, it’s the rear toe that goes out of spec. And it’s not that much out of spec on the rear toe, for the car to handle terribly…. that’s my experience in the ISF ownership for 10+ years.

Supras have always had this issue mostly because the alignment techs fail to use the factory torque specs for tightening the bolts. On the Supra, the front adjustment bolts need to be tightened to 166 ft-lbs. Few techs know this and you have to press them hard to make sure they do this right or the front end goes loose and handling goes to crap quickly. AMHIK.
Well folks looks like car is back to what it used to be like, was able to put it to the test today and she’s feeling good alright surpassing triple digits in Mexico of course.
This is interesting data. The tires in the US have a maximum pressure of 44 psi on the sidewall of the tire. I am surprised at these numbers assuming the European versions of these tires have the same limits. It's certainly possible they are different for the European market, and given the specs on the sticker, I can only assume they are. Lexus in the US would never recommend inflation beyond the manufacturer's specification. Their attorneys would have a fit if any engineer did this.

Tire Rack shows max inflation pressure of 50 or 51 psi for the high performance tires I looked up. looks like some H speed rated tires spec 44 psi. I think the tires are the same in Europe except that they specify higher pressures for very high speeds above 210 and 250kph. Guessing that's to lower the rolling resistance and keep tire temps in check at those speeds which are not unheard of on the autobahn.

Don't think so. The load and speed ratings are the same as the North America, 93 & 96 and the Speed Ratings are "Y" or Up to 186MPH (300KPH) Max inflation seems to run about 50PSI for performance tires in those sizes.
However, unlike the American tire sticker that only lists one recommended tire pressure, the European sticker lists three for different speeds
Just checked the sidewall of my PS4S and it's marked 50PSI.
