Will these block access to my jack points?

No. Side skirts are designed to mount inboard of the factory jack point locations. Before installation, verify your vehicle's OEM jack point positions and use them as your reference during fitment — this ensures you maintain full access for floor jack and jack stand placement.

Do I need to paint these before installation?

The skirts ship in raw FRP condition, so you'll want to sand and prep the surface before applying primer and your chosen topcoat. Paint them before install for the cleanest finish and easiest masking.

How much does ground clearance change with the 2-piece design?

Ground clearance depends on how low your ride height sits. The Vector profile hugs the rocker line without aggressive downward extension. Measure your current ride height, then test-fit the skirts to confirm clearance over speed bumps and driveway approaches — especially important if you're running lowered suspension.
