Will this wing stay stable at highway speeds?

Yes. One-piece carbon fiber construction is rigid and mounts directly to OEM roof attachment points, which are engineered for factory aero load. Secure all fasteners firmly and the wing will remain stable across your driving range.

What mounting hole pattern does this use?

This wing is designed to use existing OEM roof mounting locations. Before installation, verify your roof has the standard factory mounting holes by comparing to your vehicle's service manual. If holes are missing or filled, drilling may be required — use the OEM hole pattern as your guide.

Does the wing create trunk lid interference or affect rear visibility?

The Bart profile is designed for roof mounting and does not extend into the trunk lid area. Visibility is not compromised. If your vehicle has a power rear window or spoiler already installed, verify clearance before fastening to avoid contact during operation.
