They look bad-ass in the pics, but in real life: The door sills have a protective OEM plastic cover on them. They have ribs so you don't want to put the stickers in them. So you need to take off those OEM covers, wheich leaves you without scuff protection. Even if that's not an issue, for example if you replaced the OEM ones with flat aluminum or just the painted sills themselves, I'm betting that they would get scuffed up in a short amount of time just from their location. Lot of work for some tacky stickers.
Other than that, yeah I like em
