BD7'16 was a dog of a car compared to its '14 and '15 variants. Primary change? Lower CG, smaller shocks.
I'm not saying it's not better - I'm saying that lower CG needs to be considered amongst other things too. If you change just the CG, but leave roll center and all your springs and damping the same, you'll end up with a much stiffer car setup that probably won't work.
