I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

Does anyone have the part number for the upgraded sway bars and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

Does anyone have the part number for the iDrive 8.5 system so I guess I'll just live with it for now.

Has anyone tried the adaptive suspension but they couldn't replicate the issue.
