Will this wing stay stable at highway speed?

Yes. The wing is engineered for aerodynamic stability once properly mounted and fastened to factory drilling points. Verify all fasteners are tight before driving, and refer to your vehicle's service manual for proper torque specifications.

How do I match the factory mounting hole pattern?

Reference your vehicle's OEM trunk lid hole locations. The wing is designed to use existing factory drilling points; measure and mark holes before fastening to ensure alignment.

Does the wing interfere with trunk access?

The RBS profile is designed with minimal trunk clearance impact. Open your trunk slowly after installation to confirm there is no interference with the panel. If adjustment is needed, loosen fasteners and reposition the wing slightly forward or aft before re-tightening.
