Will this wing maintain stability at highway speeds?

Yes. The Speedster profile is engineered for balanced downforce without creating lift or flutter. Secure mounting to factory attachment points ensures stability at sustained speed. Verify your mounting surface is clean and fasteners are properly torqued before driving.

What's the mounting hole pattern, and will it align with my factory trunk lid?

This wing uses the original mounting locations on the rear deck. Before installation, verify your trunk lid has no interference by test-fitting the wing in the closed position. Sand the mounting surface thoroughly and confirm all fastener holes align before final assembly.

Can I apply clearcoat directly to the primer, or does it need additional prep?

Sand the surface with appropriate grit and apply your chosen primer or paint system per manufacturer guidance. The FRP gelcoat layer accepts both urethane and acrylic systems. Proper surface prep ensures paint adhesion and a seamless finish.
