Will this interfere with the trunk seal or bumper gaps?

No. The Speed Style profile is designed to sit below the factory bumper edge without disrupting seals or gaps. Verify clearance with your specific bumper by measuring the lip position relative to the fascia attachment points before final installation.

Do I need to drill through the bumper to install this?

Installation method depends on your vehicle's existing OEM mounting holes. Check your bumper's factory attachment locations — this lip is engineered to use them. If drilling becomes necessary, reference your vehicle's service manual to avoid brake lines, sensor wiring, or structural supports.

How stable is an FRP lip at highway speed?

FRP construction delivers solid rigidity for highway driving when properly secured at all mounting points. Ensure fasteners are tightened evenly and check them periodically, as vibration can loosen hardware over time. Inspect the underside for debris or impact damage before each season.
