What mounting hole pattern should I use?

Reference your vehicle's factory trunk lid to confirm existing or pre-drilled holes. If drilling new holes, use a pilot bit and measure twice — FRP panels are rigid but can crack if overtightened. Check your service manual for the recommended fastener pattern and spacing.

Will this interfere with the trunk lid when it closes?

The flared wing profile is designed to sit above the trunk lid surface. Test fit the wing in the closed position before drilling permanent holes. If there is any interference, shim or reposition the mounting points slightly forward — minor adjustment prevents binding and ensures smooth operation.

How stable is this wing at highway speed?

FRP wings are rigid and lightweight, minimizing vibration under load. Proper fastening at all mounting points is critical — ensure every bolt is snug and evenly torqued per your vehicle's service manual. A loose installation will cause flutter; a solid mount will hold steady.
