Default Torque Steer

I have a 2008 still with 67k on the clock. I Got it from carmax @ 58k. When I purchased the car it pulled right. They aligned it(1st time) and it was not better.I loved the car and bought it anyways. Fast forward 3k miles from purchase date and I brought the car to subaru becausre it was still pulling and they began checking the tires and noticed i snagged a nail. Replaced one tire but Subaru felt it was within spec obviously because they replaced it and said nothing about replacing them all to match. They aligned (second time) the car and gave it back.
To my consternation, the car was still pulling to the right. The dealer said swapping the tires left to right caused the opposite to occur. when I brought it back to them again(3rd time) and they realigned it, finding that it had fallen out alignment...

They then gave it back. Fast forward 4k miles and the passenger right tires is worn so badly from toe in, it will need replaced. Carmax then aligned (4th time) it and showed me how close to factory the specs were, satisfied.They swap itThe tire to the back. Fast forward 1500 miles and now both back tires are destroyed and so is the tire in the front passenger side again... Figuring it was tires, I went out today and bought a whole new set of tires.

At some point it started pulling left, i think this started happening when the swapped out the worn front tire to the back .

It only pull on accel or under load though . At coast, it goes straight.

Carmax put wheels from a 2013 STi on the car with brand new tires, same problem, only now it pulls right instead of left.

they have replaced lower control arm bushings, and reset the rack (it was loose and missing bolts)

it has been aligned numerous times and always trues up, but doesnt go straight, whats the deal...
ALSO, if you dont have a clue (like me, or the dealerships i took it to)
I guess i need a good reputable body shop to verify angles, lengths and frame rigidity, any suggestions.

Are any of the struts blown/leaking? If so, start there. Suspension geometry is changing under load/stress and could explain why alignment looks on spec while on the alignment machine. It could also explain the uneven wear on the tires etc. Worth a shot.

no struts are blown or leaking. however, the car seems to bottom out pretty easily.

If they are still the stock units from the factory it's time to replace them. They usually last about 60K miles and you don't know how badly the previous owner beat on them or the type of roads they drove on. I had an issue similar to this with an aftermarket set up, but that was due to springs binding and not sitting properly.

it seems to be under any level of acceleration, obviously hard accel makes it worse, what exactly did you swap out?

Front control arm bushing kit
Rear trailing arm bushing kit
Front sway bar bushings - 20mm
Rear sway bar bushings - 17mm
Manual Transmission Shifter Stabilizer Bushings
also whiteline rear differential and subframe bushings
and Cusco engine mounts
Most noticeable were the engine mounts and the front lower control arms. Much more responsive and sold feeling. Afterwards i heard no more clunks and had no more torque steer

my set up did the same thing under hard acceleration; pulled to the left and then I got a new alignment, still pulled to the left, so I got new tires and had my rims checked none were bent or messed up and then got a new alignment, the car pulled right after that then straightened up a bit. I got tired of the set up causing me problems and didn't want more of them so I upgraded them with coilovers and haven't had a issue since then. Maybe I got lucky and didn't have any suspension pieces bent.

Sorry I didn't clarify more earlier

UPDATE!

took the car to west end allignment, they set the alignment and discovered a 0.0 degree camber on the drivers side and .6 degree negative on the passenger side.

they sat me in the car and set it up negative 1.5 all around. HUGE improvement.

West end broke a stud on my car but other than that the guy waited an extra hour after closing for me so props.

took the car to coach craft and discovered that the car probably ran something over on the passenger side and required some kinds of repairs. Coachcraft is epic BTW.

car needs new bushings, and probably shocks and springs.

idk what the previous guy did but he wore the shocks and springs out so bad and unevenly the car squats wierd and pulls.
