Real-world results

We have installed these Bilstein B1 units on numerous E39 builds. The feedback is consistently positive – tighter turn-in, reduced NVH and a properly settled front end once paired with fresh dampers. Customers appreciate the fit-and-forget reliability and the genuine OE feel.

Perfect when refreshing suspension

If you are renewing front shock absorbers or coil springs, replacing the upper bearing plate at the same time avoids future labour and eliminates the common source of front-end clunks. Bilstein B1 accessories are designed to complement Bilstein dampers for a complete, factory-correct result.
