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

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.

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 are the stock rubber motor mounts for the E30 M20 engine - 325e and 325i. These are the original spec full rubber mounts. The M20 has a fatal flaw especially when the motor mounts are worn. The engine can shift and contact other things in the engine compartment, mostly cooling-related parts. This is especially troublesome on the 1984-1987 models as the alternator belt and blades can cut into the lower radiator hose. 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).

For more serious track or street cars we recommend our HD motor mount kit with reinforcing cups - click here. These are a stiffer mount to begin with (coming from the Euro 635CSi) and the aluminum cups give additional strength especially for the side-side shearing loads that you get from cornering.

These stock rubber motor mounts are sold per mount .

This item fits the following BMWs:

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
