Hi Davy,
As far as I can see the front-rear weight distribution is a function of the design and in particular the position of the engine’s centre of gravity. So if you have equal weights left to right then that’s as good as you’ll get.
Out of interest – what did you actually measure front to back? In my opinion the Traction is a mid-engined car so it would be interesting to see how close to 50:50 it is.
Regards
