Drivetrain Mounts and Upgrades for BMW 3 Series E30 (1984-1991)

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.

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.

Condor Speed Shop took the hard work out of removing and reinstalling your differential! If you've ever taken out your diff, you know how much of a pain it is to get the bolt holes to line up during re-installation. They never seem to line up perfectly, and getting the bolts to go in can be time-consuming. Condor's diff studs are designed to make your life a little easier. The diff will line up and lift right into the holes every time. 38mm studs are used with OEM or regular subframe bushings. 45mm studs are used with the 12mm riser subframe bushings. You'll need to pull the driveshaft to drop the diff. Use thread locker during install. Recommended for street or race use. Kit includes: 4 Studs 4 Washers 4 Lock Nuts

These specific mounts are designed for those with clearance issues on extremely low E30s. They are 20mm taller than OEM mounts to add necessary clearance to ensure the oil pan sits above the stock subframe. Under hard braking the OEM rubber mounts allow the m20 to lean forward. Not only do these solid UHMW replacement mounts stiffen the engine and drivetrain, but they also raise the engine by 20mm, dramatically changing the responsiveness and raising the oil pan height of your E30. UHMW is an excellent general-purpose plastic with a unique combination of wear and corrosion resistance, low friction surface and impact strength. It is resistant to chemical attack and moisture absorption and retains key physical properties to -30 C.

The E30 rear subframe is held into the chassis by two bolts going through these rubber mounts. A lot of suspension motion, chassis flex, and driveline torque has to go through these two points, which makes them notorious for failure. When they do, the subframe will move around, playing havoc with your suspension's alignment and settings and making a very annoying clunk. These are direct replacement rubber mounts, sold as a pair. This item fits the following BMWs: 1984-1991 E30 BMW 318i 318is 318ic 325e 325es 325i 325ic 325is M3
