The Subframe Bushing Inserts? False, those help all the time. The subframe bushings are huge and super soft. I, and most who have installed them, notice the back end of the car feels more stable and planted in every driving scenario, not just being aggressive.

And for the JXB Diff Bushing Insert, look at how much that thing moves at all time. Again, limiting excessive movement (but not going full racecar solid bushings) makes for a more controlled, pleasant driving experience at all times.

Steeda / Fenfab Subframe Bushing Inserts and the JXB Diff Bushing Insert should be the first mods done to these cars. No matter how you use it. And they are less than $400 in total. No brainer.

First off your using the wrong terminology, Steeda and Fenfab offer rear subframe bushings. The subframe bushings and bushing inserts do nothing handling wise, there is no way that they could help, they're not connected to any suspension parts. I was referring to the subframe bushings, but my comment also applies to the subframe bushing inserts I guess to. The JXB inserts make a difference, but aren't as important as a subframe brace.

Steeda and Fenfab sell Subframe (to Body) Bushing Inserts. They most certainly do affect handling, if the subframe (holding all the rear suspension) can move around independent of the body, handling will feel off. The stiffer you make those mounting bushings, the more precise the handling. You can feel the rear of the car moving around less, even in normal turns during normal driving.

The JXB Diff (to Subframe) Bushing Insert helps during simply accelerating as the differential is moving less and power is transferred to the wheels more quickly. These changes were noticeable. Yes a Diff (to Subframe) Brace helps mount it even more solidly, especially for the 3-bolt guys.
