as i been browsing other forums i come to find that you can make your own lip buying products from home depot and store like that. i saw them on wrx's and ALOT on miata's.
here are some links to pictures:

cool. was is it u need to buy?

 

My boyfriend did it because his car is too low for a real lip. Its just like a think piece of rubber. Its actually nice because it protects the bumper when he scraps in driveways. But if you are going for looks I personally wouldn't do it. It starts to sag where there are screws or whatever you are using to keep it on.
