Preparation
Before starting the installation, ensure your vehicle is parked on a flat surface. Gather all the tools and materials listed above. It is advisable to wear safety glasses and gloves throughout the process for protection.
Step 1: Lift the Vehicle
Using the jack, lift the front or rear of the BMW 340i. Secure the vehicle with jack stands to ensure it is stable and safe to work under.

Removing the Stock Suspension
Step 3: Disconnect the Brake Line and ABS Sensor
Carefully disconnect the brake line and ABS sensor from the stock strut. Use brake cleaner to clean any debris around these connections to prevent contamination.
Step 4: Remove the Strut Assembly
Loosen and remove the bolts securing the strut assembly to the steering knuckle and the top of the strut tower. Be cautious, as the strut may still be under tension.
Step 5: Remove the Springs
Using a spring compressor, safely compress the spring and remove it from the strut assembly. This step is crucial to avoid injury from the spring tension.
