I do not know whether to change
Your stock springs are none progressive springs, meaning that they have the same coil tension on every coil. Eibachs are progressive springs, meaning that different coils have different tension/compression rates. This means that although the Eibachs are longer, they will compress more, thus a lower ride height.
