Does this wing use the factory trunk lid mounting points?

Yes — the RKS wing is engineered to mount at the OEM hole locations. Verify your trunk lid is straight and unbent before installation; any damage will affect fitment and alignment. Reference your vehicle's service manual for proper fastener torque specifications.

How does FRP hold up to UV exposure over time?

FRP remains stable in sunlight when properly sealed. Paint or clear coat protects the panel and prevents UV degradation of the primer. Wash regularly and avoid prolonged exposure to harsh chemicals; a quality automotive topcoat will extend the life of the finish indefinitely.

Will the three-piece design stay stable at highway speeds?

Yes — each section fastens independently at factory mounting points, creating a rigid assembly. Secure all fasteners per your vehicle's spec; loose bolts or improper torque are the only cause of instability. Check fastener tension every few months during the first season of driving.
