Do these panels affect jack point access?

Factory jack points remain accessible. Verify clearance on your vehicle before final installation, and always use proper jack stands when servicing. The M1 Sport profile sits lower but does not obstruct OEM service areas.

What prep is needed before painting?

Sand the surface to promote paint adhesion, then clean thoroughly to remove dust and debris. Follow your chosen paint system's surface prep guidelines for best results. FRP accepts standard automotive primers and topcoats without issue.

Are factory fasteners compatible, or do I need new hardware?

Use fasteners appropriate for your vehicle's original rocker mounting system. Verify bolt hole alignment with your specific mounting points during a dry fit, then secure with hardware rated for rocker panel attachment. Refer to your service manual for fastener specifications.
