Will this wing stay stable at highway speeds?

FRP wings are rigid when properly mounted and secured. Confirm mounting hole pattern alignment with your existing roof attachment points or factory reinforcement areas before drilling. A solid mount eliminates movement and wind noise.

Does the roof wing interfere with a trunk lid or hatch?

The D1 profile is mounted at the roof peak, not the trunk lid, so clearance is determined by how far the wing extends forward and backward. Measure your actual roof dimensions against the wing footprint before installation to verify your specific fitment needs.

What surface prep should I do before painting?

Sand the surface with appropriate grit to remove any dust or imperfections, then clean thoroughly before applying your chosen primer and topcoat. Follow your paint supplier's prep guidelines for best adhesion and finish.
