Eibach Pro-Street-S Coilover Kit for BMW Z4 E89 Roadster
The Eibach Pro-Street-S Coilover Kit gives your BMW Z4 E89 Roadster a lower, more controlled stance with everyday usability. It replaces the standard suspension with height-adjustable coilovers, so you can fine-tune how low the car sits and how it responds on the road.
Ride quality stays tight and controlled, with more confidence in fast bends and better stability at speed. The threaded front struts and adjustable rear units let you dial in the look and feel you want, from subtle drop to a more purposeful setup.
Key benefits
- Lower, more aggressive stance without losing daily comfort
- Improved cornering grip and stability
- More precise, confident steering feel
- Height adjustment front and rear for a tailored setup
- Quality components designed to work with the Z4 chassis
Note: Not suitable for 4WD models or cars with electronic suspension. Some factory wheel setups may need spacers for proper clearance, and extra original parts may be required during installation.
