Poly Fxx M3/M4/M2 Motor Mounts

These mounts are designed for BMW F8X M4, M3, and M2. They are rebuildable and the polyurethane bushing inserts can be easily swapped out for a different hardness.

These mounts are made from CNC machined 6061-T6 billet aluminum combined with high quality polyurethane.

Revshift mounts are the most durable and reliable mounts on the market. To further ensure the strength of our mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum pieces. The polyurethane compounds that Revshift uses are among the best for automotive use and exceed the material quality of possibly all other automotive polyurethane manufacturers.

Two assembled motor mounts
Heat sleeve for exhaust side mount

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 white: Drastically stiffer and stronger than OEM rubber. Moderate increase in NVH. Most commonly used on dedicated track cars.
(NVH = noise, vibration, harmonics)
