Adding weight for stick lipos

[Bungleaio]

I've almost completed the changeover for stick lipos in my car but I'm wondering how much weight I should be adding to the lipo side. In my touring car I've put about 150g on the lipo side to that the chassis balances and seeing as I'm using pretty much identical electronics in the pred I'm thinking I should be addding the same to that.

Just wondering how much you are adding to your preds?
