Will this interfere with my trunk lid when it opens?

No. The AF-1 profile is designed to clear the trunk lid arc. Verify clearance by opening and closing your trunk with the wing in place before permanently fastening.

What mounting hole pattern does this use?

This wing uses factory trunk mounting locations. Before drilling or fastening, compare the hole positions on the wing to your trunk surface to confirm alignment with your OEM holes.

Does FRP stay stable at highway speeds?

Yes. FRP is rigid and lighter than OEM steel, which reduces unsprung weight. Proper fastening at all mounting points is critical — verify all bolts are tight before driving, and recheck after the first 50 miles.
