Nothing "premium" about them. There are gaps that look terrible. They don't fit the car snugly, to fix this I would have to buy 3m of tape and reattach the protection. The normal bolts that come with the guards are useless, there are no nuts so you need to buy other mounting hardware over the 3m glue to make it fit. Also, there is an extra hole on the front fenders that doesn't even come close to matching my Challenger even though they were made specifically for this year. Don't waste money on them. I will look for a replacement with a more solid brand.
