Will the wing stay stable at highway speeds?

Yes. The one-piece construction and factory mounting points provide solid lateral support. Once fastened through the stock holes, the wing won't deflect or rattle. Confirm all fasteners are tight before driving; check them again after your first 50 miles.

What's the mounting hole pattern?

The wing mounts directly to your vehicle's factory rear body holes. Before installation, verify that your specific build year hasn't deviated from the standard hole spacing — snap a photo of the mounting area and cross-check against the mounting tabs on the wing itself.

Will the wing interfere with the trunk lid?

The RS profile is designed to clear the trunk lid throughout its full range of motion. However, vehicle-to-vehicle variation in bumper fitment and ride height can differ slightly. Mock-fit the wing before drilling or fastening, and open and close your trunk through its entire arc to confirm clearance on your setup.
