If you are looking at this we presume you have one so thank you very much for your purchase.
As stated on the website. Hardware is NOT INCLUDED. It can be done with the bumper on the car but you must remove the factory underside aero. We also suggest having someone help you it will be a lot easier to install!
We suggest using All Stainless Steel bolts, washer and nuts for this. Holes are drilled for 6M bolts and you may need to open them up if the hole is not large enough. Some people drill them open use 8M bolts too. Use washers where it is applicable on bolt on both sides of the lip. OR or use a flange bolt on outside and a washer on the inside. DO NOT USE self tapping screws. We recommend mocking up the lip first and mark the hole for it. REMEMBER you must push inward toward the bumper putting this lip on. IT DOES NOT FLEX and goes over the lower bumper cover. So you mush push toward the bumper when mocking it up AND with applying the double sided tape.
So yes, double sided tape is also needed in this install. Use 3M VHB Double Sided Automotive tape (DO NOT USE ANY OTHER BRAND) we suggest to use this one here: https://amzn.to3rzraV1 for the top side and this one here: https://amzn.to/3wxkqqb for the ends. Or find them at your local auto parts store.
Make sure the surface is clean with no wax or ceramic coat on it. We encourage to use a Adhesion Promoter like this here: https://bit.ly/3An4CZV or other top brand to help your double stick tape to adhere along with using a heat gun to make sure it is tacky. Be sure not to burn the clear coat off with the heat gun!
(ignore the smaller tape this this was the original install) then fold the red part over and tape it down on the other side like this:
