Will these skirts interfere with my jack points?

Side skirt placement is designed around factory rocker geometry. Before installation, verify your OEM jack point locations on the undercarriage and test fit to confirm clearance with your lifting equipment.

What should I do to prepare the surface before painting?

Sand the surface with appropriate grit and wipe clean before applying your chosen primer and topcoat. Follow the paint manufacturer's recommendations for FRP substrate preparation.

Do these change ground clearance?

Side skirts run along the rocker panel and do not affect ride height or suspension clearance. They add visual width and definition without altering your vehicle's ground clearance characteristics.
