Will this wing maintain its shape at highway speeds?

Yes. FRP construction is rigid and designed to handle sustained aerodynamic loads without flex or vibration. Ensure all mounting points are torqued securely per your vehicle's service manual to maintain stability across your full speed range.

What prep work is needed before painting?

Sand the surface to create tooth for adhesion, then clean thoroughly to remove dust. After that, apply your chosen primer and topcoat system. Standard automotive surface prep applies — reference your paint manufacturer's guidelines for grit and product compatibility.

Does the 5-piece design affect trunk lid clearance?

Check your trunk lid operation before final torque-down. The wing's profile and extension are designed for clearance, but verify full open/close articulation in your specific setup. If interference occurs, spacers or bracket adjustment may be required — reference your service manual for mounting hole locations.
