Will this wing stay stable at highway speeds?

Yes. FRP construction is rigid and resists deflection under load. The W-1 profile is designed for balanced downforce without excessive drag. Confirm all mounting fasteners are torqued to factory specifications per your vehicle's service manual before driving.

What mounting holes does it use?

The wing mounts to factory anchor points on the rear quarter panel and trunk lid. Before installation, verify your vehicle's OEM mounting hole locations align with the wing's pre-drilled pattern. If custom drilling is needed, reference the factory service manual for structural reinforcement areas.

Will the wing clear the trunk lid when it opens?

The W-1 geometry is designed to clear the trunk lid arc on standard configurations. During dry-fit, open and close the trunk fully to confirm clearance. If you have roof-mounted equipment or non-OEM trunk modifications, test fit is essential—the wing's extension may require adjustment to your specific setup.
