1999 Porsche 911 payload capacity
Payload is not the same as towing capacity. Where both GVWR and curb weight exist in the catalog, payload is GVWR minus curb weight (or the manufacturer payload field when present). Payload covers people, cargo in the truck, hitch equipment, and trailer tongue weight — not the full trailer weight.
Payload figures are not available for this model year in the dataset.

* Payload = manufacturer payload when present, otherwise GVWR − curb weight. Towing capacity is a separate rating and is not the same as payload.
What affects the rating
Higher figures usually need the tow package, the right axle ratio, and enough cooling. Passengers, fuel, gear, and tongue weight all eat into what you can safely pull — stay under both the trailer rating and the vehicle’s payload.
