Will these affect jack point access?

Dry-fit the skirts and verify clearance to your factory jacking points before final installation. The MB-R profile sits close to the rocker — you may need to adjust jack placement slightly or use a jack pad that spans a wider area.

Do these bolt to factory locations?

Mounting points are not specified — test-fit first to confirm bolt-hole alignment with your vehicle's rocker panel. Drill or fastener type will depend on your mounting strategy once fitted.

What prep work do I need before painting?

Sand the surface with standard automotive prep — 220–400 grit should level any mold lines or shipping marks. Wipe clean, apply your base coat, and clear coat per your paint system's instructions.
