M42 Poly Motor Mounts

If you're looking for stiffer motor mounts for your M42 E30 (318is), this is it. We have used and tested all different types of bushings over the years, and found the Revshift poly bushings to be the best on the market. Choose your hardness.

Fitment: E30 M42 ONLY

Revshift mounts are the most durable and reliable mounts on the market. CNC machined billet aluminum flanged ends are embedded deep in the urethane which prevent the isolated ends from separating under extreme loads. Utilizing class 14.9 alloy steel removable screws, these mounts will hold your transmission in place for a lifetime. To further ensure the strength of these mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum ends pieces.

These mounts have removable screws for ease of installation. We recommend using loctite on the threads during installation.

Hardness
80A black: Slightly stiffer and stronger than OEM rubber. No additional NVH. Great choice as an upgraded stock replacement (OEM+).
95A green: Significantly stiffer and stronger than OEM rubber. Minor increase in NVH. Excellent for enthusiastically driven street cars and track cars.
70D TEAL: Drastically stiffer and stronger than OEM rubber. Moderate increase in NVH. Most commonly used on dedicated track cars.
(NVH = noise, vibration, harmonics)
