The ideal 50:50 is based on the following:
- A FR config car is difficult to achieve 50:50 in the first place, so about as good as it gets for a 3 box saloon/sedan
- For road cars driven by the general population, 50:50 is a good compromise in terms of safety (some understeer with the ability to add throttle induced oversteer) whilst being reasonably nimble, and stable under braking with weight shift forwards.
