Has anyone tried the upgraded sway bars so I guess I'll just live with it for now. I've been noticing a strange rattling sound from the front end lately.

I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module. There's a massive DIY thread on this exact issue over in the DIY section.
