Will this wing stay stable at highway speeds?

Yes. FRP wings like this are engineered for highway use and hold up well once properly mounted and secured. Ensure all fastening points are tight and verify your mounting holes align with the factory locations on your vehicle before final installation.

What's the mounting hole pattern for this wing?

The panel uses factory mounting locations on your vehicle. Before drilling or fastening, confirm your vehicle's OEM trunk lid or body mounting points match the hole pattern on this wing. This prevents unnecessary modification and ensures a clean fit.

Will the wing interfere with a trunk lid or hatch when it's open?

That depends on your trunk lid clearance and how you route the fasteners. Measure your trunk opening and the panel height after test-fitting to confirm adequate clearance before permanently securing it. Some installations may require recessing fasteners slightly to avoid contact.
