Eibach Pro-kit springs for 2009- e89 Z4. I've had in my car for about 6000 miles. No issues whatsoever, still in good working condition.
Recently upgraded to KW and no longer have a need for this.
Asking $185 shipped in ConUS. Local pick up in San Jose or Mountain View.

- After switching to 19" wheels but on stock springs
- After installation of Eibach Pro-kit, car sits lower, and looks a lot nicer. Ride comfort was not compromised at all.
