Will this lip interfere with my bumper's existing trim or splitter if I have one?

The Global style is designed to sit flush with OEM body lines. If you're running a factory bumper cover, verify the lip clearance by test-fitting before final installation. If you have an aftermarket splitter, check its height relative to the lip attachment points to avoid binding.

Do I need to drill new holes, or does it use the factory mounting locations?

This lip is engineered for factory integration and uses existing mounting points. No drilling required if your bumper cover is stock. If your bumper has been modified or replaced, reference your vehicle's OEM service manual for the original anchor point locations.

Should I adhesive-bond or mechanically fasten this to the bumper?

Mechanical fastening through factory mounting points is the recommended method and provides the most stable, long-term result. If you choose to supplement with adhesive, prep the surface and allow full cure time before driving. Adhesive alone is not recommended as your primary attachment method.
