Do these mount at the factory roof points, or do I need to drill?

These mount at factory attachment points — no drilling required. Bolts secure directly to OEM locations on your Sportage roof.

What kind of cargo can I mount on these bars?

These cross bars are designed to accept standard roof boxes, cargo baskets, kayak racks, and bike carriers. Your carrier's clamp attachment must be compatible with the bar diameter.

Does this come with bolts and hardware, or do I need my own?

Hardware specification not confirmed. Before install, verify the bolt size and thread pitch required at your factory roof points, then source fasteners rated for roof load if not included in your shipment.
