Boosts enhance the stats of your Drivers and Cars during a race. After qualifying and while selecting your tyres, you can equip a Boost for each Driver, and it's possible to use the same Boost for both.

Each Boost indicates the amount by which it improves your stats (e.g. Defending +10). During a pit stop, one additional Boost is consumed.

You can pin your favourite Boosts to the top of the list by tapping the heart icon on their popup.
