The back seat itself is pretty light already. If you remove the seats and the seat belt with mounts then maybe 50lbs give or take. There is no need unless your racing. But if that's the case, remove the right passenger seat as well plus the spare or inflator kit from the back plus get a carbon fiber hood. Then put helium in your tires. Lol. Just kidding. This car is already light. The worst thing is a passenger. Adults can be from 100lbs on up plus a full tank of gas is more weight than anything else you might remove. But keep in mind, too light and you lose traction thus lose exceleration which negates any benefit of less weight. Now am all wheel drive Veloster, that would be interesting.
