Does this wing need to be painted?

No. The carbon weave is fully visible and protected by clear coat from the factory. If you prefer a color-matched finish, sand lightly and apply your chosen paint system over the existing coat.

How does the mounting hole pattern compare to the OEM wing?

Verify hole spacing against your vehicle's OEM trunk lid or rear panel before installation. The GT profile may shift mounting points slightly. Use the wing as a template and mark pilot holes to confirm fit on your specific setup.

Will this wing stay stable at highway speeds?

Carbon fiber construction provides rigid support for highway driving. Ensure all fasteners are tight and torqued to your vehicle's service manual specifications. Proper installation and balanced bolt tension maintain stability and prevent vibration.
