BMW Motor Mounts for BMW Z4 M Roadster S54 (2003-2008)

Clear BMW chassis

Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

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.

Why have only one engine mount? The Powerflex Tuneable "Hybrid" Urethane & Aluminum engine mounts for the E36, E46, and E90/E92 M3 are configurable to match your current car spec. It's "tuneable" to multiple performance settings - - Street Performance with a dual-urethane core (65A and 80A bushings) - Track Performance using stiffening pins inserted into the mount. The mount does not need to be removed to insert the pins, making this a tuneable mount from the paddock. Also available is a full-race mount with a 95A black urethane core and stiffening pins. With the stiffest configuration the Powerlfex mount is a whopping 675% stiffer than a new M3 engine mount! Other BMW urethane engine mounts are made with a single solid urethane block of one durometer. This is simple and cheap to manufacture but is not ideal for most scenarios - the mount is either too stiff or not stiff enough and poor manufactuing quality leads to continued problems. Powerflex properly engineered their mount to absorb vibrations while providing exceptional strength and sheer resistance. The design uses a "soft" Red 65A urethane to absorb Noise, Vibration, and Harshness (NVH) with a stiffer Purple 80A urethane for improved strength and performance. If you desire a stiffer mount for tracking or drifting the mount can be made stiffer without removing it from the car! Unsnap the yellow retaining collar and insert the four stiffening rods. This reduces deflection in the mount and makes it stronger. Why would you want a stiffer engine mount? Mounts need to be stronger to withstand the higher stresses seen with hard driving or launching. Less deflection in the mount means a failure is less likely. The stock mounts are too soft for these types of driving and it's not uncommon for rubber mounts to break apart, mounting studs to shear off, and for the engine to move around and contact other parts (the radiator for example). Stiffer mounts help prevent these issues as well as giving better engine response, quicker power delivery, and more precise shifting (reducing the chances of a mis-shift). The beauty of the Powerflex tunebale mount is that it can be adapted for changing conditions, unlike other urethane or solid mounts which are either too stiff or not stiff enough. These urethane/aluminum engine mounts are sold as a pair. They replace original BMW part numbers 22111095444, 22116779970, 22116771361, 11811092583, 11812283798, 11817837985, 11812228298, and 11811136542. Fits on all 6-cylinder E36 325i/328i/M3 and E46 323i/325i/328i/330i/M3 (not Xi AWD), and V8 E90/E92 M3.
