Will this interfere with the trunk seal or rear bumper gap?

This rear lip is designed to sit flush with the factory diffuser area and will not create gaps or interference with the trunk seal. Verify alignment during dry fit before final fastening to ensure the bolt holes align cleanly with your vehicle's factory mounting points.

Can I adhesive-bond this, or do I need to drill?

This piece is engineered for bolt-on installation using factory mounting points — no drilling required. Adhesive is not recommended for rear spoilers on this style; the factory bolt locations are your most secure and removable option.

Will the FRP hold up at highway speeds?

FRP is rigid and lightweight; this single-piece design has no flex points or seams, so it holds stable at speed. Once primed and painted, the gelcoat adds UV resistance. Inspect mounting bolts periodically to maintain security on longer drives.
