We just went through a long discussion with someone who is making suspension changes to his SC Targa. See this thread: https://forums.pelicanparts.com/porsche-911-technical-forum/1174139-trying-decide-suspension-setup-my-sc-targa.html
I'm in the minority, but I do not like the RSR/Tarrett solid front bushings or spring plate bushings. I would not install them again. I drive my car regularly and do hundred mile plus highway runs. On typically rough highways and side roads, they definitely transmit more noise and harshness to the cabin.
For a primarily street car, I strongly advise to stay with rubber bushings in the front A-arms and rear spring plates.
