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

No. The RR wing profile is designed to clear the trunk opening. Verify fitment by checking clearance with the trunk fully open before final fastener torque.

Does this use the same mounting hole pattern as the OEM spoiler?

Yes. This wing is engineered to use factory mounting points on the rear deck, eliminating the need for additional drilling. Inspect your deck for rust or debris around the holes and clean thoroughly before installation.

What should I do before painting?

Sand and prep the surface with your choice of sandpaper and primer before applying your chosen topcoat. Refer to your paint supplier's specifications for surface preparation steps to ensure proper adhesion.
