my standard ST Escort Cosworth with bolt in roll cage was 1350Kg. unfortunately I didn't get the corner weights.

The only other info I have is after removing seats, carpets etc, not much good if you have a road car. However here it is.
with me in the car, I'm 83Kg and 15ltr fuel in tank.

Front R 330kg.
Front L 370kg.
Rear R 249kg.
Rear L 260kg.

My car is LHD and the front doors were still steel, the doors weigh up to 40Kg the pair.
