Will this wing stay stable at highway speeds?

Yes. FRP construction provides the rigidity needed to resist vibration and flexing at speed. Confirm mounting hole alignment with your vehicle's trunk lid panel before installation to ensure proper fastener engagement and load distribution.

Does the trunk lid need modification to fit this wing?

Not necessarily. The R1 wing mounts to factory or factory-equivalent mounting points on the trunk lid. Before installation, verify that your trunk lid geometry matches the OEM standard — any dents, prior repairs, or aftermarket lids may affect fitment and require surface prep or minor adjustment.

What surface prep is required before painting?

Sand the surface thoroughly to ensure paint adhesion, then clean away all dust and debris. Apply your chosen primer and paint system per the manufacturer's instructions. Proper prep is critical for long-term finish durability in all weather conditions.
