    There are definitely impact forces acting on the joints. Some joints see more impact forces than others though, and I think because of the rear trailing arm's orientation, the RTAB sees more impact forces than those control arms which are closer to perpendicular to the car's axis.

    Anyone think a stiffer RTAB would affect stresses imparted to the RACP? I know there have been arguments against poly bushings in the rear because they are believed to accelerate RACP failure, but considering the RTAB is isolated from the subframe assembly, is it logical that a stiffer bushing here actually reduces RACP stress?

    it also sees a lot of twisting force when power is trying to be applied to the ground.

    but as far as impact absortion goes, i find the car rides smoother and absorbs bumps better with the spherical RTABs.

    this is a great discussion topic.

    from my unprofessional engineer's mind, the more i think about it, the worse poly is as a choice for the RTAB location. ultimately, they restrict trailing arm articulation as they will bind under the angles asked of them - how this translates into RACP stress, i can't seem to visualize - but, i can see how it might cause RTAB pocket stress. and as such, rubber bushings with aftermarket 'limiters' should do exactly the same thing.

    in this respect, the spherical should actually be the best choice as it will restrict movement even less than the OE rubber bushings.

    i can't recall if vince (creator of the VinceBar) has mentioned this or not. i'll have to ask him. i'm pretty sure he runs the BW sealed spherical RTABs on his supercharged M3.

    I actually don't care about this lol

    Interesting idea.



    Now if it was a Prius part, I would have the urge to burn down whatever it was installed in as it would forever be tainted.

    i confirmed that he does indeed have these.

    which does not mean anything, however he is an ME and has done probably the most thorough independent testing and research on RACP failure, so.... take that for what it's worth.

    i think tesla runs these too.

    While the bushings themselves might be good, I don't like Moog. Is there a better version available?
