Will this interfere with my trunk seal or rear hatch clearance?

The diffuser profile extends modestly below the stock bumper line. Before installation, verify trunk and hatch operation with the panel test-fitted in place. Minor trim adjustments to surrounding seals are occasionally needed depending on your vehicle's wear — check clearance before final fastening.

Should I use adhesive or drill through the existing mounting points?

This panel is engineered for your vehicle's factory mounting locations. Drilling through OEM points keeps the install reversible and avoids permanent body damage. Apply panel adhesive as a supplementary measure only — prioritize mechanical fastening at all factory holes for highway stability.

How does FRP hold up at sustained highway speeds?

FRP is rigid and impact-resistant when properly secured to all mounting points. Ensure fasteners are tight and verify the panel sits flush across its full width before highway driving. Any gaps or movement will amplify wind noise and reduce aerodynamic benefit — take time to dial in the fitment.
