Once the hard cased lipo saddles are out, and i can get hold of some then i will make a new battery tray for them, which you can adjust forwards and backwards like the current tray.
I am not able to get corner weights so i cannot give you a rear weight percentage. With the movable battery tray we find this is a very good extra tuning aid for the car, as you are moving around the heaviest item in the car.
When we ran the 3 gear car, i had to try to get as much weight to the back of the car to get rear end grip, even added 55grams of lead onto the rear shock tower to help, but with the 4 gear gearbox thats in the production S2 its the opposite it generates lots of grip so no lead needed, and i normally run my cells in the mid or forwards position to lose some rear end grip.
S2 uses B4 wishbones btw.
