If I turn both adjusters in the same amount the drivers side is always a lot lower(obvious tilt). For example if both sides adjusters have 2" of travel I have to turn the the drivers side in at least an inch to even out. If I turn the pass side in more it starts to look like no engine in the car.
I would check out the driver's side rear spring and the passenger side T-bar anchor point very carefully before new T-bars in front. And if you could borrow some wheel scales, that would be very useful to know the weights on the corners.
