I just got my car back after replacing all the rubber bushings with elephant rubber. It rides like new. I did A arms inner banana arm and rear torsion bar rubber. Also top of front strut. went to 21 torsion bars at front and 26 rear (factory). It's perfect and the bars are not too stiff even for my old targa. My inner banana bushings were falling apart. No more clunks or squeeks. I have Koni gas front and rear and these seem to work well even with the stiffer bars. I highly recommend this suspension refresh for any of our older cars that are not going to be tracked.
