Will this wing stay stable at highway speeds?

Yes. The wing mounts securely to factory anchor points and is engineered for aerodynamic stability. Verify all fasteners are properly torqued before driving, and reference your vehicle's service manual for the correct torque values.

Does the wing clear the trunk lid when it opens?

The Deva profile is designed to sit above the trunk opening. Measure the height of your factory trunk lid at full extension and compare it to your installation setup to confirm clearance in your specific build.

What prep is needed before I paint this?

Sand the surface with standard automotive grit, wipe clean, and apply your chosen primer and paint system. Follow your paint manufacturer's surface preparation guidelines for best adhesion and finish quality.
