I dont want a stiff ride where all the panels are rattling. I want a glass smooth ride, and handling like a go kart isnt important to me. QUOTE]
Well the ride is not that stiff. You are comparing rubber to poly bushing. Right now its a good time to change all the suspension/body bushings because it's almost 20 year old! If you want the handling you will have to go with the poly bushings.
Doing the suspension work on the TR is very costly because all the labor work involved but after its done it pays off because you will noticed a big difference!
