I been searching for solid rubber mounts. I know bmw use to sell solid rubber mounts. I don’t want to buy poly mounts. IDoes anyone know where can I buy solid rubber mounts.

I found some OE style rubber ones with a quick search. BBR makes replacement rubber diff mounts.

The Z3M unit is 33 17 2 228 425, cheapest vendor is like $220 plus shipping, expect $300 when all is said and done, or if you get one in the US.

Didn't say it made sense, but it's the off the shelf performance option. I would personally go another route.

I have done Powerflex soft polyurethane for around $40-50. It's 2 pcs sandwiched between 2 large washers. Very easy installation, great fit and I didn't notice an increase in vibration or noise. People have been reporting that certain replacement OE rubber bushings are actually larger in diameter and are breaking the diff cover when they press them in. So definitely check the bushing if it needs to be pressed in.
