Another great product from Eibach. Although it isn't stated in the description, the dampeners are in fact mono-tube. Fit and finish is top notch! I am (for the most part) at the lowest height setting, and it isn't too extreme. Wheel gap has been eliminated and I can safely travel over speed bumps without scraping. Installation took a little longer only because I was adjusting the ride height and corner balancing the car. I haven't had a chance to really push the car but am giving 5 stars as I know the folks at Eibach had a CR-Z test mule. I'm sure there is some compromise in extreme performance since this is a street setup.
