    Stick with stock RTABs or go to bearing style from Dinan, Synchrodesignwerks, fallline, turner.

    No poly for engine, tranny, fcab, rtab.

      Recordings of solid diff bushings do not capture how deep the sound travels into your skull. Imagine a dentist drill powered from your diff! It travels deep inside your soul and takes no prisoners.

          Ok solid diff bushings are officially no go for me after that description. To be clear, you are including the front diff bushing being poly an absolute no go too, right?

            Just dove in for a quick research frenzy after this comment and decided that I will now do condor monoball rtab (aka synchro design) as condor will have black friday sale. Thanks for advice.

              The stock front diff bushing is sold separately and low cost to replace unlike the ones on the cover. No reason to go aftermarket here unless you want to go solid for a race car. They last ~100k miles which is a very reasonable service interval. Now, it is annoying that they don't offer the diff cover bushings without the cover, but those covers are aluminum and can crack fairly easily.

                I'm just here to confuse you and make you second guess yourself, my car came with poly diff mounts from the previous owner and I like it lol. I have some solid mounts that I will likely sell.

                  That's why I like: solid subframe + oem front diff bolt bushing + e36 m3 bushings for the diff cover, it's been very good to me!
