Bilstein B3 OE-spec Front Road Spring for BMW Z4 E85 E86 2002-2009 - Part No. 36-241477

Refresh the front end of your BMW Z4 with this Bilstein B3 OE-spec front road spring. It is a direct-fit, factory-rate replacement that brings back correct ride height, sharp steering feel and everyday comfort on E85 Roadster and E86 Coupe models. Ideal when a spring has snapped, sagged or you are completing a front suspension overhaul on 2.2i, 2.5i, 2.5si, 3.0i and 3.0si variants.

We rate this spring highly for stock-height setups and OEM-plus builds. We have installed these on customer Z4s at MJ Modifications and feedback has been consistently positive for composure, refinement and true-to-original fitment.
