mechanic test drove it he said "pretty straight" NOT! when i accelerate over 45+ mph i felt my car was pulling right and it pulls left when decelerate
tire pressures are even, tire wear? i dont see much of wears n i know it wont really effect much.. unless i have 20% meat on my tire which is not the case.
i spent $80 they couldnt fix it?
could it be something to do with chassis subframe or control arm?
left and right SAI and included angle are really uneven..

does anyone have clue?

Sounds like rear tires are the issue.

I would take it to another shop to get aligned.

Maybe borrow wheels and tires from a fellow s2000 owner to trade out? Put their wheel and tire set up on your car and see if it does the same thing. If it does, then it's a suspension/chassis issue. If not, it's a wheel/tire issue.

What you need to do is track down and isolate the variables that could cause the issue. My first response would be tire pressure, but since you've already checked that...

Your alignment specs look good. What tires are on the car? Are they the same tires left and right or at all axles? Same model and speed and load rating?

swap your tires from left to right. Sometimes tires can have a pull when your alignment is straight. Your car will usually drift to the right a "little" because of the slope in the road the way it's paved for drainage too.
