Drivetrain Mounts and Upgrades for BMW E34 M5 S38 3.5L

If allowed in the rules these solid aluminum transmission mounts offer many advantages over a 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). 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 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 mount unless a corresponding solid 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
• Grade 10.9 stud - fear not, big turbo owners

ECS Tuning's Polyurethane Transmission Mounts are designed to address the vital role of transmission mounts in your vehicle's suspension. The factory mounts are notorious for failures that can result in over-revving, mis-shifts, and in extreme cases, potential chassis damage. Our polyurethane mounts provide a robust solution, engineered for both street and track applications, guaranteeing enhanced performance while eliminating concerns about torn mounts.

Polyurethane stands out with its exceptional toughness, durability, and impressive wear resistance compared to rubber. It also exhibits resistance to water, oil, and grease while retaining its original shape even when subjected to significant compression. By reducing deflection, polyurethane facilitates effective power transfer. While there may be a slight increase in NVH (Noise, Vibration, Harshness), the benefits far outweigh this minor compromise in ride comfort. With a polyurethane durometer of 70A, our street mounts are versatile, offering both daily driving comfort and track durability. For more track-oriented enthusiasts, we provide stiffer mounts with an 80A durometer rating.

For a hassle-free installation, we supply a comprehensive DIY guide. ECS Tuning ensures that you are fully supported from start to finish.

These are the stock rubber motor mounts. When motor mounts begin to wear the engine can shift and contact other things in the engine compartment, mostly cooling-related parts. This is especially troublesome on older models. Don't neglect your motor mounts! A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. 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).
