Nope they use factory fender liner hardware and they come with brackets to reinforce where needed. With a 90degree Phillips screwdriver, you don’t even need to take the wheels off.
I have to admit that I can't stop thinking about how nice these look.
I noticed there was another company making mud flaps (for the i30N) and they have the N logo on them too. The mounting hardware looks similar to my eyes.
Do you think these look about the same?
