Will this wing maintain stability at highway speeds?

Yes. The wing is engineered for high-speed performance and designed with proper mounting geometry to deliver downforce without creating lift or flutter. Ensure fasteners are torqued to your vehicle's service manual specifications before driving.

Does the trunk lid close with the wing installed?

The LBW design is proportioned to clear the factory trunk lid. Before final installation, verify clearance with the lid in the closed position. If your vehicle has an aftermarket lid or modified latch, test fit first.

What mounting holes does this use?

Reference your vehicle's OEM mounting hole pattern before installation. The wing is designed to use factory trunk attachment points; verify hole alignment and spacing on your specific setup. Use stainless steel fasteners to prevent corrosion.
