add nothing. You don't need no stinking badges.
let your mods speak for the car besides nobody has ever said, "cool badges"...lol.
in all seriousness, its your own OCD you need to satisfy, then by all means satisfy it, get some round t4r stickers.
I thought about getting either t4r stickers or trail edition stickers as close to my vehicle color as i can get (magnetic grey) so I can ghost it, so people can't see the sticker unless you are actually looking for it. Its a little trick from my import ricer days. Although these days, ghosting it would imply taking a sticker and overlaying it with vinyl, so you only see a imprint of the sticker....but we didn't have vinyl way back when.
