I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the upgraded sway bars and honestly it feels like a completely different car. Does anyone else have this issue?
