Will this wing interfere with the trunk lid when opening or closing?

No. The Zero style profile sits at the leading edge of the trunk lid and clears the full travel arc. Verify clearance by opening and closing the lid during installation — there should be zero contact at any point.

What mounting holes does this use?

This wing uses the factory rear deck mounting locations. Before installation, locate the OEM mounting holes on your vehicle and confirm they align with the wing's attachment points — no modification required if they match.

How stable is carbon fiber at highway speeds?

Real carbon fiber is rigid and extremely stable at speed when properly mounted. Tighten all fasteners securely and verify they remain tight after 50 miles of driving — vibration can loosen bolts on any aftermarket part during the first few drives.
