Will this wing interfere with trunk lid operation?

The M4 profile is designed with factory trunk clearance in mind. Verify your trunk lid opens fully before final fastener tightening. If you run a spoiler or aftermarket lip, test the full combination to confirm closure.

What mounting hole pattern does this use?

This wing uses factory trunk lid mounting locations. Reference your service manual to locate and prepare the OEM holes. If your trunk lid has been modified or drilled previously, ensure the existing holes align with the wing's mounting points before fastening.

How should I prep the FRP surface before painting?

Sand the surface with appropriate grit to promote paint adhesion, then apply a suitable primer and topcoat per your paint supplier's instructions. FRP surfaces benefit from proper scuffing and degreasing before any finish work.
