50/50 weight distribution is something that the marketing department promotes. Especially BMW. Note that that it is
static weight distribution that is being promoted so maybe it improves handling when the vehicle is stationary. Also something that never gets mentioned in those adverts is where that mass is located; that is, having 40% of the mass in front of the front axles and 40% of the mass behind the rear axles is very different from having 80% of the mass between the two axles but both are 50/50 distributed.
That figure "50/50" is front/rear. There is never any mention in adverts about left/right balance which in road cars is kinda difficult unless one removes the driver. If one is serious about this one will get the car corner balanced but it depends on one's ability to make use of what
I believe to be an incremental benefit.
Have a read of this:

Also have a look at this and listen to the explanation about weight, braking and aero distribution:

I am suggesting that in a BRZ/86/FRS weight reduction from anywhere is more significant than worrying about distribution.
