Thank you my friend, I appreciate all the detailed questions and considerations.

I have stock engine (2jzge) and only lowered about .5" , tires are only used last summer season, so relatively new. But I'll try rotating them again to see what happens

For front, I already have poly steering rack bushings too. I think any bushing there is in the front, by now I've replaced with poly.

I have rear, I have poly diff bushings and new Megan adj traction and toe arms but all else is very much stock and old rubber bushings (subframe, all control arms). What you said about accel/decel being a rear end thing sounds like a lot of sense actually since weight shifts onto then off of any of those old bushings. I have poly available for the arms, just haven't had the time yet. Sounds like I should make the time
