The konigsport is made from mild steel, but fully height and stiffness adjustable
The silverline is made from stainless steel, which is a good idea as the mild steel set will rust, but not as good on track (stainless tends to keep the heat inside more, desireable for manifolds, not for shocks). The Regular silverline is only height adjustable, the Silverline x is fully height and stiffnessadjustable
