my mugen wannabe abs lip from ebay has held up well. i am careful so ive only scraped it once real bad but no real damage done, it just had to be pressed back down into place. the two screws holding it in place towards the middle are gone (ripped out from the scrape) so now its just being held in place with 2 screws on either end and some styrofoam blocks between the bottom of my bumper and the top of the holes of the lip (on the backside of the lip). this way if i scrape the styrofoam will just compress and the lip will slide up, then i can just press it back down into place and find some more styrofoam to keep it in place. my front tires are barely tucking under my fender, about 4" clearance between ground and lip. ive learned to avoid shit roads
