Will this wing interfere with my trunk lid when it opens?

The ducktail design sits low enough to clear a fully open trunk lid. Check your trunk angle before final installation — if you run a custom hatch or have modifications that alter the lid geometry, verify clearance during dry fit.

Does this use the same mounting hole pattern as the factory trunk?

Yes. The wing is engineered to use the OEM trunk lid attachment points, so you won't need to drill new holes. Verify the hole locations on your specific trunk before drilling any fasteners.

Will this stay stable at highway speeds?

FRP wings are designed to handle sustained freeway driving without flex or movement when properly fastened. Use appropriate fasteners rated for your mounting surface and refer to your vehicle's service manual for fastener torque values to ensure a solid installation.
