Will the rear wing stay stable at highway speeds?

Yes. The three-piece FRP construction is engineered for aerodynamic stability. Make sure all three sections are properly bonded and that mounting points are torqued securely per your vehicle's service manual.

What's the mounting hole pattern, and will it match my OEM trunk lid?

The wing mounts to factory locations on your trunk lid. Before assembly, verify your trunk lid mounting holes align with the wing's base by dry-fitting the pieces. If any holes need adjustment, mark them now — drilling is easier before bonding the assembly together.

Does the wing interfere with trunk lid closure?

Trunk clearance depends on the exact height and angle of your installation. Test fit the assembled wing on your trunk before final bonding to confirm the lid closes without contact or binding. This takes five minutes and prevents rework later.
