[Supras] Rear end pulling left under accel

[Rockey Fox]

Since putting my new tires on I have noticed that the
harder I accelerate the more the rear end seems to
drift to the left and pulls back to the right when I
let off.
I suspect the strut rod bushings are soft on the right
side but I would like other ideas or recommendations
of what else may be causing this.

TIA,
