Do these canards come with mounting hardware?

The set includes the canards themselves. Hardware and fasteners for your specific mounting setup should be confirmed with your vehicle's OEM bumper structure and mounting points before installation to ensure proper fit and security.

What prep is needed before painting?

Sand the surface with appropriate grit to promote paint adhesion, then clean thoroughly to remove dust. Apply your chosen primer and topcoat following the paint manufacturer's specifications for FRP substrates.

Will these fit with aftermarket front bumpers or splitters?

Canard fitment depends on your specific bumper and splitter geometry. Measure the mounting boss locations on your setup against the canard attachment points before purchase to confirm compatibility with your front-end configuration.
