If you're talking about my front lip.. At first I had the mapisa front lip which is from their body kit. Once I broke through two of those I went with a front lip made for the LE front bumper but has a similar style to the FRS front lip. The actual FRS front lip doesn't reach end to end on the Corolla's bumper.
As far as installing, the black front lip installation was a breeze. I just removed my front bumper, flipped it upside down (masking the side that would be on the ground to prevent scratching the paint) and used a couple of clamps to hold the lip in place. Once I was satisfied with the fitment I used nuts and bolts to secure it to my bumper. I didn't use the screws that came with it as I didn't want the lip to rip off since my car was so low.
