Will this wing interfere with the trunk lid or rear glass when fully open?

The HM-S profile is designed for roof mounting with clearance from hinged components. Before installation, open your trunk and rear glass fully to verify clearance at your mounting angle. Adjust wing pitch during installation to ensure no contact during regular operation.

What's the mounting hole pattern, and will I need to drill new holes?

This wing uses factory roof attachment points, which minimizes new drilling. Verify your vehicle's OEM roof hole locations before purchase. Some variations may require small additional pilot holes; reference your vehicle's service manual for exact attachment specifications.

How should I prepare the FRP surface before painting?

Sand the surface with appropriate grit to promote paint adhesion, then wipe clean of dust. Apply your chosen primer and topcoat per manufacturer specs. Proper surface prep ensures long-term finish durability and UV resistance.
