I used OEM hardware and had no problems, I just added crazy glue to the 3M tape attached to the lip for additional grip. OEM part # is(82-11-0-021-339 FRONT SPOILER) BMW has it listed as front spoiler but it is the decorative skid plate. I paid $180 including Titanium Silver paint (you can't go wrong with this color it will complement any body color). When you drill the holes use 2 sizes smaller than what the intallation guide sez'. Good luck and keep us posted if you run into problems. You also can apply windshield glue on the inner lip of the plate for maximum grip and seal.
