Will this wing interfere with the deck lid when fully closed?

No. This wing is designed for standard deck-lid clearance. Verify that your mounting surface is clean and flat before installation; any warping or debris will affect final fitment alignment.

What's the mounting hole pattern, and does it match my OEM base?

This wing uses the factory deck-lid mounting points. Before drilling or fastening, confirm your deck-lid hole locations are clean and undamaged. If your car has aftermarket spoiler hardware already installed, you may need to verify compatibility with your existing fastener locations.

How should I prepare the FRP before painting?

Sand and prep the surface according to your chosen paint system's requirements. The wing ships raw FRP, so light scuffing and a clean surface will give your finish the best grip. Consult your paint supplier for specific grit and primer recommendations.
