One last quick primer on F1's new rules for 2019

Minimum Weight

In a bid to ease the disadvantage suffered by taller and heavier drivers in the past, the FIA has imposed a minimum weight of 743kg this year.

However, the driver - fully suited and booted - and his seat must weigh in at a minimum of 80kg.

If the driver/seat combo weighs in under that level, the team must fit the required amount of ballast inside the car's cockpit to bring it up to the 743kg minimum limit.

Smaller or lighter drivers may still offer an advantage however as an underweight driver-seat-car package would provide teams with the freedom to place their ballast strategically to improve performance.
