Description

BMW E90 Differential mount reinforcement 188mm E91 E92 E93

This steel plate reinforces the differential mount 188mm of the BMW E90, E91, E92 and E93 with the large type 188L differential. You will find this differential in, among others, the 318d up to and including the 325d, the 330xd, the 325i up to and including the 335i, and the 325xi and 335xi. The reinforcement prevents the mount from cracking and keeps the differential stable as soon as the power goes to the rear wheels.

These very engines are popular as a base for motorsport projects and powerful road cars. More torque means more load on the mount, and that is what this plate is made for. Whether you are building a drift car, drive a diesel with a software remap or simply want to be sure of a healthy rear axle: the reinforcement protects the mount before any damage occurs.

Key benefits of the reinforced differential mount 188mm

Installation and delivery

The plate for the differential mount 188mm is bolted in place only. On some subframes you have to drill two holes for M10 bolts. Put the car safely on a lift or axle stands, support the differential and replace the original bolts if in doubt. Tighten them to the specified torque and check them after the first few drives.

Protect the drilled holes against corrosion. For more reinforcements, take a look at chassis and subframe reinforcements, or for the drivetrain at differential. If your car has the even larger 215L differential, choose the version for the 215L differential.

More torque calls for a stronger mount: this plate keeps the 188L differential in place.

Why choose a stronger differential mount 188mm?

A 325d, 330xd or 335i with extra power puts a lot of force through the rear axle. If the differential mount cracks, repairing it is a big job. This plate made of 4 mm S355 steel prevents that; you bolt it on yourself and it is bent precisely for the 188L differential. That way you do not have to wait until cracks become visible, and you tackle the problem while the car is still healthy.

Frequently asked questions

Which engines have the 188L differential?

Among others the 318d up to and including 325d, 330xd, 325i up to and including 335i, 325xi and 335xi. Some versions were supplied with two different types, so check the type on your own car.

Do I need to weld to fit the plate?

No, the differential mount 188mm reinforcement is only bolted in place.

Do I need to drill holes?

Depending on the type of subframe, you drill two holes for M10 bolts.

How thick is the steel?

The plate for the differential mount 188mm is made of 4 mm thick S355 steel, laser-cut and bent on a CNC press brake.

Is it worthwhile on a car without tuning?

Yes. Even a standard 325i or 335i delivers a good amount of torque. A reinforced differential mount 188mm gives extra peace of mind, especially if you take the car on track now and then.

Does this plate fit a 168L or 215L differential?

No, separate versions are available for those types.
