I had the Eibach's on my previous car, but these H&R springs feel a lot better. I have much more confidence when cornering. The springs provide enough stiffness without being too stiff. My only complaint is that they could lower the front end of the car a bit more. The rear sits very nicely. Roughly a 1-2 cm more of a drop to the front and it would be just perfect!
