Will this wing stay stable at highway speeds?

Yes. FRP wings are engineered for structural rigidity under load. Ensure all mounting fasteners are torqued to your vehicle's service manual specifications and check them periodically to maintain secure fit.

Does this wing interfere with a trunk lid when opening and closing?

No interference with normal trunk operation. Before final installation, test the full range of lid movement to confirm clearance with your specific vehicle setup and any aftermarket components.

What mounting hole pattern does this use?

This wing is designed to use factory mounting points on your vehicle. Verify the hole locations on your OEM trunk lid before drilling or fastening to ensure proper alignment and fit.
