Will this work with my OEM trunk latch and deck lid seal?

Yes. This wing bolts to the existing factory mounting points on your trunk and clears the latch area. Verify your trunk opens and closes freely with the wing installed before final fastening.

How does the mounting hole pattern compare to the factory spoiler?

This uses the same factory trunk attachment locations, so no drilling or new holes are required. If you're switching from an aftermarket wing with a different pattern, measure your current holes before ordering to confirm alignment.

Is this stable at highway speeds?

FRP wings are engineered for aerodynamic function and highway stability when properly fastened. Torque all fasteners securely to spec and inspect mounting points regularly, especially after track use or rough roads.
