Will this wing maintain stability at highway speeds?

Yes. FRP construction provides solid rigidity once mounted through factory points. Ensure fasteners are tightened securely and check them after your first 50 miles of driving to confirm no movement.

Do the factory mounting holes line up perfectly, or will I need to drill?

Factory holes are pre-positioned to align with OEM fastener locations. No drilling needed. Verify hole alignment against your vehicle before final fastening to catch any clearance issues early.

What prep work is necessary before painting?

Sand the surface with appropriate grit to promote paint adhesion, then clean thoroughly before applying your chosen topcoat. Follow your paint manufacturer's application guidelines for best results.
