If the system detects even a tiny bit of slip, usually it'll clamp down that one brake momentarily and the yaw produced gives you the "loose butt" feeling.
I'll bet anything it's just a little slip

Again to get back to topic it is not between pavement and tires it's between suspension and car trust me I know the diference.
Thank you all for your help

interesting video, but what does it mean to the driver? I mean does it make the car stickier / improve handling? Is comfort improved, or sacrificed? etc.

ya they made all the bushings squishy from factory. i linked you the solid aluminum bushings i got for the rear and they work.

makes rear end more solid and predictable. no increase in harshness or noise in the ones i linked. helps keep your suspension geometry where it is supposed to be and makes car better with zero sacrifice.

Let us know what the dealership was able to find out. We are here if you have any questions.

Cool, but in the video the bushings are not the only parts that were changed. Do we need to change all those parts to get that result? Did they replace other parts that don't show in the frame? There are lots of rear suspension parts on the vendor website, some (like the arms) you can clearly see are also replaced in the video, while other parts would be out of frame.

You're in Boston....if you are driving when it's under 45 Degrees on the stock Pirelli P-Zero tires (summer, ultra high performance design and compound) the rear end isn't going to be nearly as planted to the road as it would with a nice all season tire.

I have the Pfadt trailing arms, toe arms, drop springs, sway bars and end links in my car. I opted for a poly subframe bushing instead of the solid ones. Together they make the car feel very solid. Any movement in the rear of the car under heavy throttle is just driver related now.

I would think the more hooked up the tire is the more I can feel it. I have played on damp pavement with traction control off and the tires just spin car fishtails around but I don.t feel the squirm in that situation. When its hooked up I feel the bushings flexing I know that now.

yes there are other things replaced in video....but its not the point of the vid. you see how much just that one bushing moves. and how much the solid aluminum basically replacing the bushing and just bolting the rear to the car...
