Will these side skirts block my jack points?

No. The Brizio design maintains clearance at factory jack point locations. Before final installation, verify your vehicle's jack pad position and test fit to confirm access with your specific lifting equipment.

Should I paint these before or after installation?

Either works. Painting before install gives you better spray angle and masking control in your shop; painting after install is faster if your body shop is already color-matched and you want to blend seams. Sand the primer surface lightly before paint application either way.

Do these change ground clearance?

Minimally. The Brizio skirts follow the factory rocker line closely without adding significant lower extension. If you run lowered suspension or measure ground clearance for speed bump clearance, test fit before committing to installation.
