Will this wing stay stable at highway speeds?

Yes. The one-piece carbon fiber construction is designed for high-speed stability. Before installation, verify your mounting surface is clean and flat, and ensure all fastening points are secure per your vehicle's service manual specifications.

How do I confirm this fits my existing trunk lid without interference?

Check the mounting hole pattern on your current trunk lid against the wing's attachment points. Most installations use standard factory mounting locations, but your vehicle's service manual will detail exact hole spacing. Measure twice before drilling any new holes.

What prep work should I do before installation?

Clean the mounting surface thoroughly and dry completely. If you're drilling new holes, mark and verify placement using a template or your vehicle's service manual. Apply a thin coat of clear silicone sealant around fastener holes to prevent water intrusion. The clear coat finish is pre-applied and ready to install — no additional paint or UV treatment is necessary.
