Mechanical Collection

Complete sets to add stats to all your cars.

A Collection is not a fusion system

The Collection groups sets by part type and rarity. Contribute the required parts to receive the bonus once all the set's slots are filled. It does not create a new part or raise a part's rarity.

Contributing permanently consumes the part and its upgrades. If you want to use it on a car, equip it in the Garage instead.

How to complete a set

  1. Open Collection in the Garage's lower navigation bar.
  2. Choose the rarity and part type.
  3. Select an unequipped part that matches the archetype slot.
  4. Check the bonus and confirm the contribution.
  5. Fill the remaining slots: the last contribution completes the set automatically.
Mechanical Collection has rarity tabs at the top and part types below them. Each slot accepts its matching archetype. Click to enlarge.

The part's rarity must also match the set. Compatible normal and [M] versions fill the same slot. An [M] part does not increase the completion bonus.
