Will this wing maintain its gloss finish long-term?

Yes. The clear coat is applied during manufacturing to protect against UV exposure and oxidation. Regular washing and occasional wax application will preserve the finish, just as you would maintain any carbon fiber component exposed to sun and weather.

What mounting pattern does this wing use?

Reference your vehicle's OEM rear trunk lid or body panel mounting points. Hand-lay carbon fiber wings are typically drilled to match factory hole patterns, but you should verify alignment with your specific setup before final installation.

How does weight compare to the stock rear wing?

Carbon fiber is significantly lighter than OEM plastic or composite designs. The single-piece construction also means fewer fasteners and connectors, reducing overall assembly weight. This contributes to improved weight distribution at the rear.
