it may be kinda of an oxymoron but the 50/50 weight distribution is not a myth. You can increase the balance of the car by leaving weight on the rear of the car, this will make it more stable under braking and long sweeping corners.. If you want the car to change direction quickly you can always run the rear nearly rigid and just point the front where you want it to go.
there is some middle ground.. you just have to find where you are comfortable or faster with.
