Don't drink the BMW kool-aid. There's nothing all that great about a 50/50 weight distribution, no matter where your engine is. 53/47 is a good place for the AS1 to be based on it's power level, given that the engineers wanted it to be a little tail happy under throttle.

For going fast around a race track in a RWD car, the "ideal" weight distribution is in the range of 45/55 to 40/60 depending on cg height and power to weight ratio. Staggered tire widths keeps the contact patches nearly evenly loaded front to rear for optimum cornering grip. Rearward load transfer puts a large majority of the load on the rear tires for extra traction out of a corner, and forward load transfer under braking more evenly distributes load for shorter braking distances.
