Default Wheel alingment '10 IS 350

I had new Conti Ext DWS installed, along with 4 wheel alignment. Car has slight pull to the right, went back to independent shop that performed 1st alignment and they made corrections again. It still pulls slightly to the right. What is the experience of others, should I be able to expect a neutral steer going down a flat road?

Below are the recent results after correction;

FRONT LEFT RIGHT
Caster 7.5 7.5
Camber -0.7 -0.6
Toe 0.05 0.05
Total Toe 0.10

REAR
Camber -1.3 -0.9
Toe 0.20 0.20
Thrust Angle 0.0

If there is nothing wrong with your alignment, then it could possibly be a bad tire (even though it is new.) Did you have any pull with your old tires? What you could do is swap sides with the front tires and see if it goes away or changes sides. You can't leave them this way since they are directional, but it could help you isolate the problem.

Never noticed any pull with the old tires, but they where garbage. I did swap side to side, no change, still veers to the right.
Does anyone know, do the alignment specs look OK?

Might be stating the obvious, but they did put the correct tire sizes on in the proper location. Fronts are smaller size than the rears, directional pointing the right way, etc???

What I see is that the camber is consistently more negative on the left side than the right, especially in the rear. This would likely induce a pull to the right. Unfortunately, in Toyota's infinite wisdom, camber is not adjustable on our cars. Do you remember hitting anything major on the left side?

Correct size tires are in the proper locations and the tires are non-directional.

Don't remember hitting anything on the left or right, but I purchased this car used about 8 months ago. No previous damage reported or detected.

While that is true, however there are ways around it, depending on the alignment tech's experience. For instance, the one I go has other techniques (that are of trade) which he employs to further fine tune or correct the geometry of the car (ie. adjust the camber).

I am getting mixed signals from replies. Can the camber be adjusted?

The camber is not adjustable however there are other components which can be adjusted outside of what adjustments are adjustable on the vehicle (if your tech has the experience), which can to put it in better terms, correct the geometry of the vehicle.

This is true because my alignment reports shown that the camber has moved and did not require the use of changing parts. The tech told me that there are other components (which he will not disclose because it is of trade) which can be adjusted; as long as they are within factory tolerences.

I have these tire and this is normal. I went through the exact same thing and eventually (several months) this goes away. Sorry but that is the price we pay for these tires. I think several other have had the same issue as well. After about 8k miles on these tires I have no complaints.

Your alignment should be 0.00,0.00 front toe and 0.12/0.12 rear but is not your alignment that is your problem.. many ppl here that put on other tires beside the oem get a little pulling. Mines pulled to the left with the hankooks evo v12 while I'm on the freeway.
