1280kg equals to 2821 pounds. Whats your car weight?
No driver, 30% full tank.
Removed rear seat, spare wheel, AC core and AC pump, headlight washers, EVAP, speakers and radio, other minor bits.
Sport seats, lightweight wheels, carbon fiber hatch and bonnet, lightweight battery.
Next target is 1200kg, will be hard to reach. Could remove interior as well but car would look awful without it.
