Will these interfere with jack point access?

Factory jack points remain accessible. Before installation, confirm your preferred jack location (frame rail vs. subframe) against the skirt profile. If you use frame-mounted lifting equipment, verify clearance in your specific setup.

Do I need to paint before or after installation?

Both approaches work. Many installers prefer to paint before bolting them on for easier masking and coverage. If you paint after, mask the mounting area and body seams carefully to avoid overspray on the car.

What ground clearance change should I expect?

These skirts follow the factory rocker line with minimal downward extension, so ground clearance impact is negligible compared to bumper aero or lowering suspension. Your approach angle remains essentially stock.
