BimmerWorld Aluminum Engine Mount Inserts, Pair - E82, F22, E9X, F3X

Mount inserts fill the void on top of the original rubber mounts and convert them to a semi-solid mount. Instead of a full solid aluminum mount you get a hybrid that may meet the rules for "non solid mounts". These are precision aluminum spacers that fit into the void on top of the stock N54, N55, and B58 rubber engine mounts.

The stiffer the mount the less deflection occurs in the bushing. Deflection can lead to driveline issues, damage from a shifting engine or transmission, broken motor mounts, as well as torque being used to move the engine/transmission instead of traveling along to the drive wheels. By reducing that amount of movement you make the entire platform more reliable. Due to the solid nature of aluminum these are not recommended for street use.

Fitment into the mount is very tight. This is by design and intentional to get the desired stiffness. For installation we recommend wood block and hammer or a large rubber mallet.

These are similar to the BMW Motorsport inserts sold for the M235i Racing, M4 GT4 and M2 CS Racing.

Installation Note: Each stock engine mount has a crescent-shaped rubber isolator that must be removed before installing the aluminum mount inserts.
