Will this interfere with trunk operation?

No. The GT500 V3 wing mounts to factory trunk lid anchor points and is designed to clear the trunk opening. Verify your OEM mounting hole locations before installation to confirm alignment with your vehicle's specific trunk configuration.

Does this wing mount using the factory trunk holes?

Yes. This wing uses the factory mounting hole pattern on the trunk lid. You'll need fasteners rated for your vehicle's specification — refer to your service manual for correct torque values to ensure a secure, vibration-free installation.

How stable is this wing at highway speeds?

The GT500 V3 design is engineered for stability across normal driving speeds when properly fastened to the trunk lid. Confirm that all mounting points are tightened to spec and that there is no movement in the assembly before driving — any flex will cause noise and potential loosening over time.
