5. McLaren are considering which upgrades to develop for the car for the 2020 season. The below table shows the cost of various upgrade choices available. (NB. all units must be made before the success of an upgrade is deemed successful or not.) The laptime benefit of an aero upgrade is 15 ms/point. The laptime benefit of weight reduction is 35 ms/kg.
