82-92 F-Body, includes: Front end link bushings, Tie rod end boots, panhard bar bushings, front & lower control arm bushings, and also the bushings having to do with the shocks and struts. (not keen on what those are called)

I am hoping to feel a very significant difference! I am sure the stock rubbers are over due for the graveyard, and these go even further (polyurethane). Anyone have this kit installed or a similar number of replacement poly bushings? I already have KYB GR2 shocks/struts, and Spohn SFCs - think I will feel this mod?
