The only “bushings” I haven’t changed are the body mounts on my car. Every other bushing was changed two years ago when we removed AHC. I bought brand new OEM front lower control arms, blackhawk front upper arms, trail tailor upper and lower rear arms, I have Timbren bumpstops front and rear, icon stage 4 adjustable shocks all around, all new sway bar end links (extended trail tailor), Deltavs rear panhard bar drop bracket. Maybe I’m missing something but there’s kit a single old bushing on my car besides the body mounts which look very healthy (it didn’t live in a hot climate that dry rots plastics and rubber…I know I have several cars I bought from California, Texas, and Nevada). I don’t know if I agree with you man. Changing out all the suspension didn’t really make that much of a difference.
