Drivetrain Mounts and Upgrades for BMW E93 M3 S65 4.0L

Clear BMW chassis

Please ensure your correct model is selected

From the factory, engine and transmission mounts are rubber and thus a wear component. Worn out engine or transmission mounts create sloppiness and a disconnect between the driver and your BMW's powerplant. If your vehicle is purpose built for the track, we recommend solid engine and transmission mounts. These have zero deflection, but come at the expense of added NVH (noise, vibration, and harshness). Poly engine and transmission mounts offer a good balance between OEM rubber and solid mounts for those with mixed purpose vehicles, offering great performance and connection with little sacrifice in terms of NVH.

We know if a soft mount offers a sloppy connection it doesn't work on the track, and a solid mount isn't acceptable as a daily driver (for most!) and set out to engineer a mount that would meet the needs for both. At the core of our enclosed design is a partially-constrained, multi-piece polyurethane bushing with precisely-set preload. This architecture absorbs and disperses resonant engine frequencies as opposed to amplifying them (like some other designs do), which results in a positive-connection, enthusiast-feel mount with the vibration.

Designed with both comfort and performance in mind, the Street-Density line from 034Motorsport is the perfect choice for the OEM+ enthusiast. These mounts feature high-durometer rubber construction to keep NVH low. However, they do not utilize the same fluid-filled technology as the factory mounts, eliminating all slop to deliver power more efficiently.

Collapsing and worn engine mounts can mean big trouble for BMWs. The stock mounts are filled with fluid that can leak or evaporate over time. That leaves the mount unstable and too flexible to properly support the engine. The side effects of a worn engine mount are: shaking and vibrating engine, driveline twist from engine torque that can break or snap bushings, and broken motor mount arms and bolts. If you're tired of replacing engine mounts you'll be very pleased with these solid rubber versions. Not only are these more reliable than stock fluid-filled mounts, they are slightly stiffer than new stock mounts thanks to a solid rubber construction (no voids in the rubber) but designed for street use so they remain quiet and comfortable. The solid rubber has less deflection than a stock mount, so no wasted engine motion. Less wasted motion gives you more torque to the wheels (it's not spent twisting the engine) and better engine response.
