Will this wing bolt to my trunk lid without modification?

Yes. This wing uses factory mounting points on the trunk lid. Verify your trunk hardware is in good condition before installation. If your lid has stripped holes or damage, you may need to reinforce those areas before fastening.

Does the wing stay stable at highway speeds?

Yes. The swept design and factory mounting points keep it secure once fastened properly. Before driving, ensure all fasteners are tight and check them again after your first 50 miles to confirm they have not loosened from vibration.

How should I prep the FRP before painting?

Sand and prep the entire surface before applying your chosen primer and paint system. The raw FRP condition means the gelcoat is sealed and ready to accept paint. Follow your paint manufacturer's surface preparation guidelines for the best finish.
