Your performance is limited by the tire contact patch vs the weight of the car. (Don't even answer if all you've got is the first order friction approximation.)
Upgraded brakes without upgraded tires first is almost certainly a waste of money. Were the old brakes incapable of locking the tires?
Brake upgrades will improve your control and brake feel. But the tire is the limiting factor.
