Will these skirts interfere with jack points?

No — the Type U V2 profile sits close to the factory rocker line without extending so far down that it blocks access. Before final installation, verify clearance to your vehicle's OEM jack points with the panels in place.

How much ground clearance change should I expect?

The Type U V2 design maintains a minimal profile and does not significantly alter ground clearance. Your approach and departure angles remain very close to factory spec.

Do I need to prepare the surface before painting?

Yes — sand and prep the surface with appropriate grit before applying your chosen topcoat or base-clear system. This ensures adhesion and a clean finish.
