Will this spoiler interfere with the trunk lid at full open?

The spoiler mounts at the rear deck panel above the trunk hinge line. Before final tightening, open and close the trunk through its full range to confirm clearance. Reference your vehicle's OEM spoiler or wing cutout to understand mounting geometry.

What mounting hole pattern does this use?

This spoiler is engineered to use the factory panel attachment points on the rear deck. Verify your vehicle's existing mounting bosses or fastener holes align with the spoiler base before drilling. If holes require enlargement, mark and drill carefully to avoid structural damage to the panel.

How stable is this at highway speeds?

FRP wings are rigid when properly secured. Ensure all fasteners are torqued to your vehicle's OEM specifications — refer to your service manual for the correct torque values. A loose wing will rattle and will not perform as intended. Once secured, the single-piece design provides consistent downforce and aerodynamic stability.
