Drivetrain Mounts and Upgrades for BMW 3 Series E36 (1992-1998)

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
• Engineered in-house and made in America

As your E30 ages, the rear differential bushing can crack, dry rot, and split. It's time for an upgrade. The ECS Tuning Heavy Duty Differential Bushing is crafted with performance in mind. Instead of using polyurethane, which is known for increasing NVH, the enthusiasts at ECS chose HD 70D rubber. This material offers a close-to-factory feel without the excess deflection of softer bushings, ensuring a pleasurable driving experience free from differential whine and excess movement.

Features & Benefits:

Eliminates Weak OEM Mount: The aging E30 chassis deserves an upgrade. Replace your old, cracked, and worn factory bushing with this HD alternative for improved performance. Perfect for Street or Track: Constructed from HD rubber instead of polyurethane or Delrin, this bushing provides comfort for daily driving while remaining effective in performance applications. Added Responsiveness: The 70D HD rubber compound is stiffer than the stock material, reducing drivetrain movement and effectively locking down your rear differential. Easy Installation: Precision-manufactured to the exact specifications of your OEM differential bushing, the ECS heavy-duty replacement installs just like the factory component. Whether you are replacing an aging factory bushing, removing excess driveline movement, or balancing performance and comfort, ECS Tuning has you covered with their Heavy Duty Rear Differential Bushing.

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).

Eliminate power-robbing rear-end flex and upgrade your E36’s dynamic handling with the Turner Motorsport Track-Spec Differential Bushing Package. On the track or aggressive backroads, factory rubber differential mounts distort heavily under load, delaying throttle response and compromising rear alignment geometry. This complete package locks down the front and rear differential mounting locations, routing torque directly from your right foot to the pavement for maximum acceleration and predictable corner exit.

Engineered for drivers who demand race-bred chassis feedback without the unrefined harshness of solid metal mounts, this package equips your E36 with a heavy-duty polyurethane upgrade. Up front, a stiff 95A polyurethane bushing is anchored by a high-strength M14x1.5 Grade 12.9 bolt, overcoming the notoriously weak factory M12 bolt setup to survive high-RPM launches and severe track abuse. Out back, 88A polyurethane rear bushings stabilize axle load shifts to keep the rear end planted through turn-in and high-G cornering. Lightweight, black-anodized 6061-T6 aluminum inner sleeves deliver structural integrity in severe racing environments.

Rubber seals are often hardened and damaged by excessive heat and constant temperature changes causing them to become brittle and crack or split. If your seal has split, replace it with a new Elring seal for long reliability and to prevent further problems.

Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!
