Will this wing mount to my existing trunk lid mounting holes?

Compare the hole pattern on this wing to your OEM trunk lid or current wing using a measuring tape before drilling. Mark out both patterns on cardboard first to confirm alignment — this prevents costly mistakes during final fitment.

Does the CSL profile add length that could affect trunk clearance?

The CSL endplates extend outward and rearward from the panel. Measure your garage height and trunk opening from the bumper to the rear window before installation. If you use a trunk spoiler as well, verify both do not interfere in the fully closed position.

What prep work should I do before painting?

Sand and prep the surface thoroughly before applying primer and color coat. The FRP arrives ready for finish — your prep work determines adhesion and durability of the final paint. Follow your paint system's instructions for surface grit and primer compatibility.
