Will this interfere with my factory front bumper or splash guards?

The lip mounts below the bumper as designed. Before installation, verify clearance with your OEM splash shield and any aftermarket aero components already fitted to your front end. Minor trimming of the shield may be needed depending on your exact setup.

Should I use adhesive or drill through the mounting points?

This lip is designed for bolt-through installation at existing factory attachment points. Drilling is not required — use the factory holes and hardware compatible with your vehicle's OEM mounting specification. Fastener torque values are in your service manual.

How do I protect the carbon fiber finish?

Apply a UV-protective clear coat after installation to lock in the weave pattern and prevent oxidation from sun and road exposure. Sand the surface lightly before application to ensure proper adhesion, then follow your chosen coating's cure time before driving.
