It wouldn't necessarily have to be ballast, it could be the battery, fuel cell, etc. But even if it was ballast, vehicles that handle and brake better, do far better on race tracks than high horsepower vehicles.

Much of the time one can't hit WOT until well after the turn, because of oversteer. If that distance was reduced because you're cars weight distribution was better, you may not be able to accelerate as fast, but you would begin accelerating earlier. Then you would brake later, carry more speed into the turn, accelerate earlier.
