Will this wing sit flush with the existing trunk lid?

The duckbill design is engineered to mount at factory bolt points without interference. Verify your trunk lid's height and any aftermarket modifications before installation to confirm clearance on your specific setup.

What's the mounting hole pattern?

This wing uses the factory OEM mounting locations on the rear panel. If you're planning additional reinforcement or custom mounting, measure your existing holes before drilling to ensure alignment with the wing's attachment points.

How stable is this wing at highway speeds?

FRP wings maintain structural integrity at normal driving speeds when properly installed and torqued to spec. Ensure all fasteners are tight per your vehicle's service manual and that the wing is centered on the mounting points for balanced aerodynamics.
