depends on if u want the front of your car to sit lwoer. a lot of people (me) when they lowere their cars have issues scraping errthang! in that case i would say, stillen or ing's front bumper. doesnt sit much lower than factory, but still gives your car a more agressive look
i really like cars looking factory, but different if that makes sense. i like picking mods to where people say "that looks good, is that factory?" which i have gotten with this stillen lip many times.
