C'mon, leave it alone! The best rear suspension setup in my opinion is to have as nearly ZERO toe change with lateral loading and with suspension compression as possible. Keeps the handling linear when pushing it hard near and over the limits of grip.

Hard to believe Toyota is still making this mistake of being "clever" with rear toe change under dynamic conditions. Frankly, I think it's stupid, gimmicky, and counterproductive.

I'm guessing they are not choosing a softer bushing to encourage dynamic changes at the limit, but instead for cost/comfort/noise reasons.
