Will these affect ground clearance or jack point access?

Side skirts sit flush along the rocker and do not alter ride height or access to factory jack points. Verify your vehicle's OEM jack locations before installation to confirm clearance with the new panel profile.

Should I paint these before or after bolting them on?

Paint after installation. This lets you color-match seams, verify fitment, and sand/prep the surface in place. Sand the FRP finish before applying primer and your chosen topcoat.

Are these bolted on, or do they require adhesive?

These are bolt-on panels designed to mount at OEM attachment points along the rocker. Use appropriate fasteners for your vehicle's structure and torque per your service manual. Adhesive alone is not recommended for primary mounting on a high-performance car.
