Will this wing interfere with my trunk lid when it opens?

The Walla profile is designed to mount on the trunk lid itself, so clearance depends on your installation height. Dry-fit the wing in its final position before permanent mounting to confirm trunk operation. If you're running an aftermarket trunk lid, verify the surface is flat and free of damage at the mounting zone.

What mounting hole pattern does this use?

This wing aligns with factory trunk lid attachment points, so you'll be drilling or bolting into existing locations. Verify your specific trunk lid surface before drilling—measure twice and use a center punch to mark fastener positions accurately.

How stable is this wing at highway speeds?

FRP rigidity is excellent for a bolt-on wing at normal driving speeds. Secure all fasteners evenly and check torque values in your vehicle's service manual. Inspect mounting points periodically for any movement, especially after rough road conditions.
