Will this wing stay stable at highway speeds?

Yes. The XTune profile is engineered for aerodynamic stability across normal driving speeds. Ensure all fasteners are torqued securely to factory specifications—refer to your vehicle's service manual for the correct values.

Does the mounting pattern match my OEM trunk lid?

This wing is designed for factory mounting points. Before installation, confirm your trunk lid holes are clean and free of debris. If you've installed aftermarket components or your lid has been modified, verify hole locations match the wing's base pattern.

What prep work is needed before painting?

Sand the surface to promote primer adhesion, then wipe clean of dust before priming and painting. Your chosen primer and topcoat system should be compatible with FRP substrates—confirm with your paint supplier for best results.
