On forza motorsport 3 I can't turn and brake hard at the same time with most dlc cars?

You can brake lightly but if you brake hard the car won't steerOn forza motorsport 3 I can't turn and brake hard at the same time with most dlc cars?
yea your tires are locking up. or your going too fast then braking. you gotta brake before the turn in the turn either no gas or little and after the turn floor it.make sure to hit the apex of the turn and youll get good laptimes
