BMW Motor Mounts for BMW 1 Series

If allowed in the rules these solid aluminum engine and transmission mounts offer many advantages over urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. These are machined from solid aluminum and have zero deflection, engine torque will cause a rubber or urethane mount to flex or deflect allowing more torque to passed through the drive line (instead of being wasted winding up the mount). When paired with our flex-free solid transmission mounts you'll get smoother, crisper shifts since the transmission is no longer dancing on the pliable mount. This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of motor and transmission mounts you will ever need. We very strongly recommend using the solid transmission and engine mounts together as a complete kit, mixing a rubber mount with a metal mount will cause undue stress on the mounting points and will lead to a failure. We never advise using a solid engine mount unless a corresponding solid transmission mount is also used.

These are a no-compromise design for all-out racing use, full solid aluminum mounts should not be used on street-driven cars since there is no material to absorb vibration making these quite harsh for regular street use (track cars don't care about noise).

Product features and benefits:

• Crisper throttle response, positive shifter location, direct power transfer
• Precision machined billet 6061-T6 aluminum housing
• Black anodized for durability and corrosion resistance
• Grade 10.9 stud - fear not, big turbo owners
• Engineered in-house and made in America

Rubber engine and transmission mounts for a street car and solid aluminum for the track, right? Well, it's not that straightforward anymore.

Stock rubber fluid-filled mounts are designed to be soft and comfortable, limiting the NVH (noise, vibration, and harshness) felt by the driver. The drawback inherent with a conventional design is driveline deflection, making it more difficult to put the power to the wheels, as well as making a money-shift or miss-shift more likely as they age. Solid mounts are exactly the opposite of this - they permit tons of NVH while offering zero deflection, making these a must have for track-driven vehicles looking to capitalize on every ounce of performance available. Enthusiasts looking to find the best of both worlds often look to polyurethane engine mounts - and many are disappointed with other designs on the market. Seeking a mount that offers a positive connection yet doesn't deform, fail, or rattle the fillings out of their mouths is frequently a lost cause.

Until now. 

We engineered these mounts with these very concerns in mind. 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. Understanding that heat is a concern for the passenger side mount's close proximity to the exhaust, we utilize a PEEK thermal insulation plate to greatly reduce heat transfer to the polyurethane, making heat a non-issue for these mounts. 

We offer two durometers, with both densities offering similar "positive connection" feeling. 60A is slightly softer and offers more of a stock feel, while 80A delivers a little more engine "feel" while under acceleration. 

Product features and benefits:

• Crisper throttle response, positive shifter location, direct power transfer
• High quality polyurethane offered in both 60A & 80A durometers (rebuildable, too)
• Resistant to water, ozone, and chemicals, maintaining its resiliency and elasticity longer than conventional rubber.
• Precision machined billet 6061-T6 aluminum housing, black anodized for durability and corrosion resistance. Grade 10.9 stud - fear not, big turbo owners.
• Thermal isolation spacer on the hot side to resist heat transfer into the poly
• Engineered in-house and made in America

Collapsing and worn engine mounts can mean big trouble for N52/N54/N55 cars. 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 wtih 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 enginemotion. Less wasted motion gives you more torque to the wheels (it's not spent twisting the engine) and better engine response.
