Every stock seat in the game gets an alternate version called "(Passenger Weight)". Fit it in the parts
menu and each seating position it covers gains its own **Tuning → Passengers** slider, 0–100 kg, default 0.
Load the back seats, put a passenger in the right-hand seat only and feel the car lean, ballast a pickup bench, or run a fully loaded bus. The weight is real mass in the physics model, so it changes the center of gravity, the weight transfer, the suspension travel and the braking behavior
