Despite the narrow front tyres teams are still aiming for a lot of weight at the front of the car. Slabs of ballast in the front wing are a popular method. Teams can run over 10Kg of tungsten in the front wing profile and have nose assemblies so heavy two mechanics need to carry them. Last year Toyota even used a trolley to help guide the heavy nose onto the car at pitstops. There are not any rules to limit the weight of ballast in this area.
