Will this wing fit without drilling new mounting holes?

Yes. This wing is designed to use factory trunk lid anchor points, eliminating the need for custom drilling or reinforcement. Before installation, verify your vehicle's OEM mounting hole locations match the wing's anchor pattern.

Does the wing's height or extension cause trunk lid interference?

The CSL profile is engineered for factory-mounting compatibility with minimal trunk lid clearance impact. Test the lid's full open-and-close range during dry-fit to confirm clearance on your specific vehicle setup, especially if you've modified the trunk hinge geometry.

What finish prep should I do before painting?

Sand the surface with appropriate grit to promote paint adhesion, then clean thoroughly to remove dust. Follow your chosen paint system's surface prep guidelines for best results. FRP benefits from a flexible primer layer before topcoat to accommodate thermal expansion.
