Will this wing mount using the factory trunk lid holes?

Yes. The mounting pattern is engineered for OEM attachment points on the trunk lid. Verify your vehicle's hole spacing before finalizing drill or bolt placement to ensure a clean fit.

Does the wing interfere with trunk operation or rear glass?

The Demon profile is designed to clear standard trunk lids and rear glass without obstruction. Check your specific trim and any aftermarket panels before installation to confirm adequate clearance for your setup.

How stable is the wing at highway speed?

FRP construction combined with factory-style mounting provides solid structural rigidity. Once properly installed and torqued according to your vehicle's service manual, the wing remains stable under normal driving conditions. Ensure all fasteners are secure and inspect periodically.
