Will this wing interfere with a factory trunk lid?

The BZ design mounts to the existing factory mounting points without modification. Before installation, verify clearance between the wing base and your trunk lid by checking how far the spoiler extends when fully seated. If you have aftermarket trunk components or a custom spoiler riser, mock up the fit first.

What surface prep does the carbon fiber need before I install it?

Sand the mounting surface lightly to remove any dust or release agent residue, then wipe clean. The carbon fiber itself comes finished — no additional prep required. If you plan to paint or apply vinyl, sand and prep per your chosen product's instructions.

How stable is this wing at highway speeds?

Carbon fiber construction provides excellent rigidity and vibration damping. The single-piece design eliminates flex points. Ensure all fasteners are secured to specification and the mounting surface is flat before driving — any gap between the wing base and body will introduce movement.
