The arachnids are great looking wheels but I finally decided to switch back to my original 19" turbine. The main reasons, which others have mentioned, were ride quality and rattles. I've gotten the 19" wheels balanced and installed but was wondering if an alignment is needed eventhough i just got it done in March. I contacted SC in Costa Mesa to inquire and they told me I do need one; they charge $245. Do I really need one? Thanks in advance.
