Recieved my seat skins (lowers) for my 2004 ZX250. The original seats have a different material in the middle ( don't know the name of this material). The backs have the same type of material. The new skins don't have this material. They are made of the same flat material. Haven't had them installed yet and not sure how they will look. Has anyone had this happen with new skins? If so how did they look?
