We have my buddies gen1 set at -3" w 8" Bolton extensions. Links are two hole (-1 & -3 according to manufacturer) and they are on the lowest setting. Drags his lower fairing a lot, and cracked the rear of the oil pan going down the highway this past summer. Going over a bridge there was a little height diff between the road and bridge. Front tire popped up a little and came down right on the rear of the oil pan. Put a huge crack in it and lost most of the oil immediately. He was real lucky cause it covered the rear tire in oil. Still set at the same height, just has to be a lot more careful.
