Rear camber assymmetry and alignment issues

Guess I'll find out the hard way once I get everything on, order my wheels and get an alignment lol thanks.

Installed rear LCAs and got it aligned, no problem with alignment values, and this time it was relatively more hard work from the technician. But after alignment car still pulls to right, even after changing front toes 0,1 degree to left both (it is still like that atm).
This pulling to right problem started right after installing coilovers + wheels. At first i thoughed that it was an alignment problem, i went to alignment shop 5 times after installing coilovers, including todays. Now i am possitive that it is not an alignment issue.
The thing is, for very small inputs to steering (like little corrections on highway), inputs to right is without resistance and left is with a little more resistance. Olso, car seems to follow the roads curve more easier to right side than left side. When i let go the steering wheel, it stays centered at first but then starts turn to right at a point and car starts to go to right like if i was steering like that. One more thing, when i am going fast (180+ km/h) on highway and go over a bump, at the moments car hops and goes down, front of the car moves to right maybe around half a meter and gets unbalanced a bit.
Feels like it is a steering issue, maybe. Any thoughts/suggestions?

When you have toe in for the rear the car will track more. Maybe try zero toe all around

I am lowered about 1,5 inch with HKS Hipermax 4 GT coilovers, 18*9,5 +45 Kojins and 255/35/18 Yokohama Neovas at all corners.

My alignment values are like this:
Toe: L R
F 0,00 -0,1 (-0,1)
R 0,05 0,05 (0,1)
Camber:
F -1,6 -1,7
R -1,6 -2,6
Caster: 6,3 -5,1
Thrust angle: -0,0

As you can see my problem is the assymmetric rear camber, does anyone have an idea why that happened?
I will get LCAs to fix it but i just want to know how it is possible. Worried about if i got a crashed car.

My other issue is, my alignment is off every time i check it (every month, this is the third time), and i havent been to track or havent driven in really bad roads. Front right cambers were -1,6/-1,6, rear cambers were -1,5/-2,5, front toes were -0,05, rear toes were 0,1. Car had alwayes been pulling to right after i got the coilovers, it is even worse now.

Do you think that caster difference is a big problem? Is there a way to fix it? And do you think it is the reason that car is always pulling to right or getting alignment off?

Thanks in advance

Your right front caster is the problem - it should not be negative!
If those numbers are right, you probably installed the top hat of the strut backwards. No wonder your car pulls to the right.

Also we've seen issues where the same shop keeps aligning the car over and over and every time it has the same results. I would try a different shop. Additionally I would think about getting corner balanced as well.

Anytime you lower one of these cars, you want to have the LCAs installed. As for the changing alignment during driving, it could be the machine doing the reading is off every time or something could be slipping. We've heard tons of complaints about the SPC arms slipping, however we've installed probably 20-30 sets of them, including on our own track car as well as lots of customer cars who drive in NYC. None of them have slipped or changed alignment settings between checks.

HKS coilovers came with pre assembled top hats, but still it can be a worker mistake, didnt even think about paying attention to that detail, but i definetely checked from top view and there was no problem (HKS logo is at outer side at both sides). Lets say it was a worker mistake from HKS, would it be possible to get nearly same camber values with same "ticks" (lets say second tick from inside) of top hat?

Yes, i made these 5 alignments at 3 different shops , only one of them seemed like paying attention, so continued with them for the last two.
Unfortunately i couldnt find any place that does corner balancing in China, maybe there is but need to know (read and write) Chinese to find it from internet.

Your caster is definitely not negative. No one can screw up that badly.
