Does this wing require a new trunk lid or will it mount to my factory trunk?

The three-piece design mounts to your existing trunk structure. Before assembly, verify that your trunk lid has adequate clearance above the inner panel and that the rear edge of the trunk can accommodate the wing's base dimension without interference. Minor trimming of interior weatherstripping may be necessary depending on your trunk's specific geometry.

What mounting holes do I need to drill?

Reference your vehicle's OEM trunk lid structure to identify existing mounting points. The three-piece assembly is engineered to use factory hole patterns where possible; confirm hole spacing on your trunk before final assembly to ensure a clean, secure fit without unnecessary drilling.

Will this wing stay stable at highway speeds?

FRP construction provides rigid support when properly secured to the trunk structure. Stability depends entirely on fastener quality and torque values applied during installation — refer to your vehicle's service manual for appropriate fastener torque specifications to ensure the wing remains secure under load.
