Will this wing stay stable at highway speeds?

Yes. Carbon fiber construction provides the rigidity needed for high-speed stability. The GT500 profile is engineered for downforce balance — verify that your vehicle's trunk lid clearance and existing mounting points align with the wing's base footprint before final installation.

Does the carbon fiber require any special finishing?

The twill weave is visible and attractive as-is, but clear coat application is recommended to protect the finish from UV exposure and road contaminants. Prep the surface by sanding lightly before applying your chosen clear protective finish.

What mounting holes does this wing use?

Verify your vehicle's trunk lid mounting pattern against the wing's base before purchase. Existing factory mounting points may require modification or adapters depending on your specific setup — measure your trunk lid hole spacing to confirm compatibility.
