99 v6 mustang I was recently given a set of bbk control arms. They have poly in them from BBK. In the box was also a poly bushing for the diff mount on the rear uca. While I had the suspension apart I put in lowering springs SR (non progressive). I have spend a bunch of time googling this forum and corral and read ll the recommendation regarding the potential for bind. I have drove the car a bit, a DD that is not pushed, and while a bit more NVH transmitted, I have not felt any rear axle bind. Does anyone have first person experience of the axle bind with poly on a DD like car? If so, I may pop the arms and put a few voids in the poly to give more flexibility.
