Swapping a chassis it the quickest, and most effective way to shed weight. Use a race car chassis to start with, as they don't generally have any normally available, but the car you put it under does, you can easily get to around 900kg on a stage 3.

What about adding weight?
I know we could do it before with grip editing but that don't work any more, The reason I ask is cause the only chassis that seems to fit a car/death trap I love is 700kg and that kills the power weight ratio, Need to get it closer to 1050kg-1150kg.

Try this:
I think it's possible with this, just change the number in weight multiplier.
