SHOULD I USE POLY OR DELRIN TO MOUNT MY DIFFERENTIAL?
We have this diff bushing available in 80a (soft poly), 95a (hard poly) and full-on delrin. The stock E36 rear diff bushings are meant for comfort. It's meant to be quiet, so BMW allows for little bit of movement for the sake of comfort. However, with its "floating" design it can fail under normal street use let alone any kind of performance driving. So we have the perfect solution. 80a soft poly is for that OEM + feel. That means you want a subtle upgrade for your street E46 without too much of a compromise in comfort, these are a happy medium. 80a are designed for the street enthusiast. 95a is great for dual purpose aggressive street and track applications. Delrin bushings are generally best for race application only.
