Drilling front bumper not necessary. I installed my used GFX front lip by just snapping into place and using the existing 5 screws and 2 push through pins (one on each end of lip) from the original OEM lip. I didn't even replace the tiny 3m tape on each side of the lip the fit was perfect. Just make sure all tabs on lip are intact. Very easy install.
