Will these interfere with my factory jack points?

No. These rockers are designed to sit outboard of the factory jack point locations. Before installation, verify your vehicle's jack point access by consulting your owner's manual to ensure clearance in your specific setup.

What's the best way to prep FRP before painting?

Sand the surface and clean thoroughly to remove dust and oils. Apply your choice of primer, filler, and topcoat. Consult your paint supplier for product compatibility with FRP substrates to ensure proper adhesion and finish quality.

How much ground clearance do these add?

GT-1 skirts extend the rocker line outward with minimal vertical rise. Your actual ground clearance depends on suspension setup, ride height, and road surface. Measure the lowest point of these panels once installed to confirm clearance for your driving conditions.
