I received my blue P90D MX this week and love it so far. There is a reported ~10% range penalty going from 20" to 22" wheels. Do you think that there would be further range advantage in going to 19" wheels? Other potential advantages include improvements in noise and ride quality, with the only downsides being a small decrement in cornering performance and subjective appearance (which I wouldn't care much about). Unfortunately, I already have some curb rash on the driver's side rear wheel from going through a fast food drive through and not yet being used to the shear bulk of this automobile.
