Personnally, I never bottomed out with my Eibachs and I'm on the stock bump stops , the ride with EDC on confortable mode does'nt feel more harsh then stock , that's the main reason why I'm so happy with them. Also when it was time to choose which springs I wanted , price was not an issue , I went with Eibachs because I've readed many good reviews of them and also because I had Eibachs on 2 of my previous cars and was really satisfied! You probably can't go wrong with Dinan but I can tell you that I honestly does'nt see any down side with my Eibachs and keep in mind that I live in Québec, the streets here are as ugly as it gets !
