Bilstein B4 RH Front Suspension Leg 22-183903 for BMW Z4 E89 2009–2016

Bring your Z4 back to its sharp, planted best with the Bilstein B4 right-hand front suspension unit. This OEM-spec replacement bolts straight onto the E89 platform and restores the crisp steering feel, confidence in corners and day-to-day comfort you expect from a well-sorted BMW.

We run B4s on our own builds and customer cars, and the feedback is consistently positive for commuting, touring and fast B-road driving. If you want factory-level quality with long-term reliability, this is the smart choice.
