    I had it apart a while back - still fine. they have a metal sleeve so the bushing itself doesn't actually move, so maybe that's why it never squeaked.

        This just means Nando isn't driving the car at all!

        Any soft poly bushing will get beat into, same with powerflex.

        Only substitute is group N subframe and Z3M or IX diff bushing.

        I was up above it, Now I'm down in it ~ Entropy - A Build thread.

          I have two e30's one for the street and one the other for the track. The track car has poly everywhere and it squeaks like everyone here has mentioned. The street 1990 coupe is an 325i and the P.O installed poly engine, diff, trans and trailing arm bushings in poly and it felt and sounded like I was ridding on a train. I left the poly trailing arm business in, added Treehouse FCA bushings in Poly and replaced the engine, trans and diff bushings with OEM rubber and its sweet. the noise is gone but the turn in is crisp. That car still has the original springs and street shocks. its a good combo. I do not know the brand of rear Trailing arm bushing ( its green) but its quiet.

            I used Condor Delrin for all of my bushings and mounts. If you're worried about NVH then don't go delrin. But they don't squeak.

              I've run rear end bushings from Lencas (old r3v vendor), AKG, Revshift (x2 cars), and Garagistic.
              The AKG and Garagistic were solid, the others are 95a.

              Revshift has a bad reputation for shipping times and their guibos. I have had great luck calling to order, and not ordering during black friday/boxing day sales.
              Their bushings are top notch though, installation is a breeze, teflon lube packets included.

              My Garagistic stuff had some issues with the solid subframe riser bushings. Material doesn't seem very durable, I installed with a rubber mallet and the lip snapped off so I had to basically machine/make a separate top for it.

              The Lencas stuff was crap. Held up well but was machined polyurethane, so nothing was concentric (especially the RTABs)


              I sold my iX with all revshift rear and was happy with that setup.

              My iS has garagsistic solid subframe bushings (12mm riser), AKG delrin diff mount, and Revshift 95a RTABs.
              I have new Revshift 95a subframe riser bushings and 2x 95a diff mounts in box to go on at some point this year.


              That said, if I ordered something set today, I'd run stock RTABs for the squeak. I don't think you'd notice a difference in feel between stock and poly RTABs.

                haha, actually I've driven it pretty regularly the last few years. Ironically, when I was taking photos for one of the ix suspension threads, I noticed my passenger side inner CV-boot is likely ripped (the Achille's heal of the ix). Recently we've had awesome days that I really wanted to take it out, but I don't want to damage the CV joint, and having worked 80+ hour weeks recently, I just don't have the time to mess with it unfortunately..
