I called Eibach and they mentioned their eibach prokit is a linear springs and not progressive but the shared document says otherwise
Yeah, I always thought the Pro Kit looked linear and just took their word for it being progressive. Did he happen to say what the spring rates were?Yes i did mention that their website and the other vendors listed them as progressive but the person over the phone reconfirmed with the R&D guys who actually worked on it and he mentioned their sportline kit is progressive which i very evident from the pics
From the little I know of...no, at least not at this level of analysis. This analysis relates to the first order oscillations, dampers related to the second order.Does ride frequency change in relation to damper setting as well?
