Will this interfere with my trunk lid or rear hatch?

No. The roof wing mounts at the roofline; hatch clearance is standard. Verify your specific mounting points during fitment to ensure proper alignment with your roof panel edges.

What mounting hole pattern does this use?

The wing is engineered to use factory roof mounting points. Confirm the exact hole spacing with your installation guide before drilling to avoid misalignment.

How stable is this at highway speed?

FRP construction provides solid rigidity once mounted correctly. Stability depends on proper torque and alignment during installation—loose or misaligned mounts will cause flutter. Follow the fastener spec sheet included with your kit.
