lets see..hmmm lips..
you got a pretty good veriety of choices on front bumper lips:
:si lip

:home depot lip

: DA lip

:accord lip?

:EG lip (mugen)

:VW lip


im liking the vw lip the most out of all, the only thing that bothers is the line in the middle, but im sure you could cover that up and paint it. if you put on a lip you might as well paint your bumpers too so you could get a nice clean look IMO. finally if you do decide to paint the bumpers, dont forget to purchase that spray that helps the paint adhiere to the bumper.
