Grow your Garage
Mechanical Collection
Complete sets, level them up and add stats to all your cars.
Contributing does not create a new part
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. Completing the set raises its level and frees the slots, so you can complete it again and increase the bonus. It does not create a new part or promote rarity: that is what Part Fusion is for.
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
- Open Collection in the Garage's lower navigation bar.
- Choose the rarity and part type.
- Select an unequipped part that matches the archetype slot.
- Check the bonus and confirm the contribution.
- Fill the remaining slots: the last contribution completes the set automatically, raises its level and frees the slots for the next round.
Locked parts don't appear among a slot's candidates. To contribute one, unlock the part first.
Set levels
Every set has a level. When you fill the last slot, the set goes up one level and the slots become free again. The cost never changes: each level asks for the same parts of the set, at the same rarity.
- Level 1 is worth the rarity's base bonus, listed under Base bonus per set.
- Each new level adds 10% of the base bonus. The gain is always on the base, not on the previous level.
- There is no maximum level. Duplicate common parts now have a permanent use.
- Slots in progress do not count. The bonus only increases when the set is completed again.
| Level | Common Engine (base +1) | Mythic Engine (base +12) | Common Electronics (base +0.2) |
|---|---|---|---|
| LV. 1 | +1 | +12 | +0.2 to each stat |
| LV. 2 | +1.1 | +13.2 | +0.22 to each stat |
| LV. 3 | +1.2 | +14.4 | +0.24 to each stat |
| LV. 5 | +1.4 | +16.8 | +0.28 to each stat |
| LV. 11 | +2 | +24 | +0.4 to each stat |
A set with a level keeps its center icon lit and shows the LV. badge at its base. Hover over the icon to see the level, the current bonus and how much the next level adds. A set you have not completed yet shows only the set bonus.
Required parts
| Set | Archetypes |
|---|---|
| ENGINE | Surge, Anchor, Vector, Flow |
| TRANSMISSION | Rush, Anchor, Vector, Flow |
| TIRES | Rush, Surge, Vector, Flow |
| SUSPENSION | Rush, Surge, Anchor, Flow |
| AERODYNAMICS | Rush, Surge, Anchor, Vector |
| ELECTRONICS | Rush, Surge, Anchor, Vector, Flow |
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.
Base bonus per set
| Rarity | Conventional set | Electronics set |
|---|---|---|
| COMMON | +1 to the part type's stat | +0.2 to each of the 5 performance stats |
| UNCOMMON | +2 to the part type's stat | +0.4 to each of the 5 performance stats |
| Rare | +3 to the part type's stat | +0.8 to each of the 5 performance stats |
| Epic | +5 to the part type's stat | +1.4 to each of the 5 performance stats |
| Legendary | +8 to the part type's stat | +2.2 to each of the 5 performance stats |
| Mythic | +12 to the part type's stat | +3 to each of the 5 performance stats |
| Exotic | +16 to the part type's stat | +3.8 to each of the 5 performance stats |
Engine benefits Speed; Transmission, Acceleration; Tires, Braking; Suspension, Stability; and Aerodynamics, its namesake stat. Electronics benefits all five performance stats.
These are the set's base values at level 1, before levels and Mastery effects on Collections, which multiply the bonus already increased by the level. The bonus is permanent and applies to all your current and future cars, starting with races formed after completion.
