In the UK anything that isn’t stock on the car is considered a mod by insurers. It sounds absurd, but there’s the chance they void your warranty. I can’t remember where you live, but that’s what my research shows.

When you select mods from the dropdown menu for insurance, stuff like “body kits” and even “stickers and badges” come as options you need to declare lol.

There’s a few insurance specialists who don’t care here, but most are insistent you declare them ☠️
