PB&J mod on poly upper control link bushings
I am currently doing a poly suspension upgrade (among other things) and have the rear upper control link bushings that I did not intend on installing when it occured to me there had been a few discussions and some success with the PB&J rubber bushing mod in the past.
My thought is, would the PB&J mod would be beneficial with poly upper control link bushings? By using this mod on the poly bushings and it relieving tension in the upper control links, would I be recreating the same effect as say oem rubber bushings with the benefits of the poly compound? The other interesting thing about these poly bushings is that they are 3 piece with a softer compound on the outside and a harder compound on the inside... so it seems to me that the hole drilling might have a larger effect than say a single compound rubber bushing?
I welcome any comments and observations as I'm curious if a test wouldn't be appropriate whether it be by me (since I am technically replacing the upper bushings with oem at least) or a more qualified individual with this extra set of poly bushings since I will already be pulling the old bushings out.
The PB&J mod..

you wont find any. you have to bite the bullet and buy a whole new arm with bushings in it. Contrary to popular belief I have poly in all my links and the car is very predictable. However I am in the process of getting a panhard bar and tri link setup since there is still room for improvement....
