Bilstein 21-24 BMW M3 G80 B1 Module - Active to Passive Suspension Conversion Kit

Bilstein is well-known for their suspension components, and their B1 Module kit is designed to help you make a specific kind of upgrade on your 2021-2024 BMW M3. If you're looking to swap out the factory electronic dampers for a set of non-electronic Bilstein shocks or struts, this conversion kit is what you need. It's specifically engineered to bridge the gap, allowing you to install passive dampers while keeping your car's computer happy.

The main challenge when removing factory electronic suspension is avoiding dashboard warning lights. This Bilstein B1 Module kit addresses that directly. It's designed to plug directly into your M3's factory wiring harness, effectively tricking the car's system into thinking the original electronic dampers are still in place. This means you get the benefit of a passive suspension setup, often chosen for its simpler maintenance or specific performance characteristics, without the annoyance of fault codes.

Bilstein includes all the necessary components and instructions to make the installation as straightforward as possible. This kit is built to OE quality standards, ensuring it integrates properly with both your vehicle's harness and any Bilstein shock absorbers you choose to pair it with. It's a well-built solution for M3 owners wanting to transition their suspension system.
