They’re fine, they’re not worth $100 but I understand with shipping and such it’s probably a alright deal. They only stick out maybe 1.125” and that’s being VERY courteous given the m sport skirts have a indent body line on the side skirt so it’s almost flush with the door at the the end of the day. Doesn’t come with screws so get some stainless .75 screws to install given a 1/4” sticky tape strip will only assist in so much.

As a BMW tech who has been installing OEM M-Performance kits for the last 10 years these rockers are a great deal for the quality. They fit like a real ones. The only gripe if you’re really picky as they are just slightly rippled compared to OE.
