is the lip only attatched by two screws and tape? if i'm wrong can someone please post the other points of installation. thank you

 

You also use the bolts that attach the bottom of the bumper to the under side of the car. There should be some spacers as well. I think there is an installation write up (by xviper) in the UTH section.

 

Yes, you bolt the lip from the bottom (two bolts near the center of the car, about 20" apart is enough), double stick tape down the entire lip length, then 2 screws on the sides into the stock bumper. If done right, it wont budge.

You want 70% of the strength to come from the tape. The bolts/screws are there to make it easier on the tape. The reason is, if you bottom out, and your lip gets pulled, it wont rip the stock bumper into shreds.
