Will this wing interfere with trunk lid operation?

No. The design mounts to the trunk lid itself and moves with it, so there's no interference with opening or closing. Clearance has been factored into the Wangan profile.

What mounting hole pattern does this use?

The wing uses factory trunk lid mounting points. You will need to drill and tap or use fasteners appropriate to your trunk lid construction—check your manual for the exact pattern on your vehicle's lid.

How does FRP perform at highway speeds?

FRP is rigid and impact-resistant at speed. This wing's wide stance is aerodynamically designed for stability. Paint and clear coat will further protect the gelcoat from UV and road debris.
