WHAT ARE POLY TRANS MOUNTS?
These polyurethane transmission mounts are meant for that OEM + feel. That means you want a subtle upgrade for your street car without too much of a compromise in comfort, these bushings are a happy medium. These poly mounts are designed for the street enthusiast but are also good for a track monster BMW. The price is for a pair (2 units). This poly transmission mount kit comes with everything you need to do one car. As with every product we manufacture, we stand by our products; they come with a Garagistic lifetime warranty.
WHY REPLACE YOUR TRANSMISSION MOUNTS?
These poly transmission mounts will have less movement under braking and cornering and, moreover, will not transfer much noise into the cabin which will make the ride a bit easier. These are a bolt-through design (10.9-grade hardware); Hardware has a nylon insert, to ensure it does not back out on its own. These mounts are great for spiritedly-driven BMW streetcars. Moreover, these mounts are great for Auto-x use as well! Do it right, do it once, do it Garagistic.
Please Note: We HIGHLY RECOMMEND that you pair polyurethane transmission bushings with polyurethane motor mounts. Running poly trans mounts with OEM motor mounts can cause transmission ear failure/breakage, and adds unnecessary stress on the drivetrain.
It's also a really good idea to change your transmission fluid while you are down there. We recommend this fluid: https://amzn.to/41KYOnn . One of these is also helpful when you're doing it: https://amzn.to/3KMKtzS
WILL THESE POLY MOUNTS FIT MY BMW CAR?
