Will this interfere with my bumper or trunk seal?

The Zargella lip is designed to mount cleanly to the front bumper with minimal extension. Before drilling or securing fasteners, test-fit the lip against your bumper to confirm clearance at all mounting points. No interference should occur if the bumper is in OEM condition.

Does this require drilling into the bumper?

Installation depends on your bumper's existing mounting holes and the fastening method you choose. Examine your bumper's underside to locate available holes before committing to an installation approach. Adhesive and mechanical fastener options both work; your choice depends on your bumper design and preference for permanence.

How stable is the lip at highway speeds?

Real carbon fiber offers excellent rigidity and won't flex or vibrate under normal driving conditions. Once secured and cured, the lip remains stable at highway speeds. Ensure all fasteners are tight and any adhesive is fully set before extended driving.
