Step-by-Step Installation Process
Step 1: Prepare the Vehicle
Begin by parking your BMW X3 M on a flat surface. Engage the parking brake and loosen the lug nuts on the front wheels. Use a jack to lift the front of the vehicle and secure it with jack stands.
Step 2: Remove the Front Wheels
Once the vehicle is securely lifted, remove the front wheels completely. This will give you access to the suspension components.
Step 3: Remove the Existing Suspension Components
Using the socket set, remove the bolts securing the strut assembly to the vehicle. Carefully detach the brake line and any sensors attached to the strut. Use the spring compressor to safely compress the spring before removing it from the strut.
Step 4: Install the M Performance Struts
Take the M Performance struts and install them in the reverse order of removal. Ensure that all connections, including brake lines and sensors, are properly reattached.
Step 5: Install the Springs
After installing the struts, use the spring compressor to install the new M Performance springs. Make sure they are seated correctly before releasing the compressor.
Step 6: Reassemble the Front Suspension
Reattach the strut assembly to the vehicle and torque the bolts to the manufacturer’s specifications. Replace the front wheels and lower the vehicle back to the ground.
Step 7: Repeat for the Rear Suspension
Follow the same steps for the rear suspension. Lift the rear of the vehicle, remove the wheels, and replace the rear struts and springs with the M Performance components.

The total cost of installing the BMW X3 M Performance Suspension Kit can vary based on several factors:
- Cost of the M Performance Suspension Kit: approximately $1,500 to $2,500.
- Labor costs if using a professional mechanic: $200 to $500.
