Parts and upgrades
Six part types, consistent archetypes, and no upgrade level cap.
Choose by type and archetype
Each car has one slot for Engine, Transmission, Tires, Suspension, Aerodynamics, and Electronics. A part only fits its matching slot and cannot be used by two cars at once.
| Type | Primary stat | Also provides Durability? |
|---|---|---|
| ENGINE | SPEED | Yes |
| TRANSMISSION | ACCELERATION | Yes |
| TIRES | BRAKING | Yes |
| SUSPENSION | STABILITY | Yes |
| AERODYNAMICS | AERODYNAMICS | Yes |
| ELECTRONICS | Determined by the archetype | No |
| Archetype | Associated stat |
|---|---|
| Rush | SPEED |
| Surge | ACCELERATION |
| Anchor | BRAKING |
| Vector | STABILITY |
| Flow | AERODYNAMICS |
For conventional parts, the type determines the primary stat, the archetype determines the secondary stat, and Durability completes the set. A combination that would repeat the primary stat does not exist. Electronics use three performance stats.
Names change with rarity
The family name changes with rarity, but the archetype keeps its meaning. For example, Velkar Surge and Torqen Surge are engines of different rarities with the Acceleration archetype.
| Type | COMMON | UNCOMMON | Rare | Epic | Legendary | Mythic |
|---|---|---|---|---|---|---|
| ENGINE | Velkar | Torqen | Ignivar | Vorteron | Solkaris | Prometheon |
| TRANSMISSION | Kairon | Syncron | Nexaris | Chronex | Eternyx | Aeonexus |
| TIRES | Vantis | Gravon | Traxen | Terravax | Apexion | Gaiaron |
| SUSPENSION | Rydan | Flexaris | Dampiron | Stabilon | Aegiron | Atlasyn |
| AERODYNAMICS | Zephyra | Ventaris | Aerion | Stratovex | Tempestra | Aetherion |
| ELECTRONICS | Veltrix | Cirquon | Synaptix | Neuraxis | Quantaris | Omnisyn |
Equip and compare
- Click or drag a part into its matching slot.
- Use the item comparison to see stat gains and losses against the equipped part.
- Right-click a part to open its options.
- To use a part from another car, unequip it first.
- Equipped parts don't count toward occupied Inventory slots. Unequipping may require free Inventory space.
How upgrades work
Each upgrade level increases the part's base stats by 5%, before Mastery upgrade-efficiency bonuses. Gains are linear per level: without efficiency bonuses, +1 gives 105% of the part's base stats and +2 gives 110%.
An unupgraded part keeps the values it received when generated. Upgrade levels do not change its rarity, type, or archetype. Part upgrades have no level cap.
| Rarity | Base Credit cost for +1 | Base Scrap from dismantling |
|---|---|---|
| COMMON | 50 | 1 |
| UNCOMMON | 110 | 3 |
| Rare | 180 | 8 |
| Epic | 260 | 20 |
| Legendary | 350 | 50 |
| Mythic | 450 | 120 |
Upgrading costs Credit and Scrap. Costs rise with level; Mastery discounts can reduce them. Check the confirmation screen before spending.
Sell or dismantle a part
An unequipped part can help in two ways: Sell grants Credit; Dismantle grants Scrap. Right-click the part in your Inventory and choose an action. The confirmation shows the part's name and the total amount you will receive.
Equipped parts must be removed from the car first. The base value depends on rarity, not on the part's type, archetype or rolled attributes. The same in-game rule applies to [M] versions.
| Rarity | Base sale value: Credit | Base dismantling yield: Scrap |
|---|---|---|
| COMMON | 50 | 1 |
| UNCOMMON | 100 | 3 |
| Rare | 300 | 8 |
| Epic | 800 | 20 |
| Legendary | 2,000 | 50 |
| Mythic | 5,000 | 120 |
The action consumes the part and its upgrades. Selling does not return Scrap; dismantling does not return Credit. Contributing to the Collection also consumes the part, but helps complete a set and grants permanent attributes instead.
How do upgrades affect the return?
An upgraded part returns its base value plus 25% of the total standard upgrade costs, from +1 through its current level. Selling uses the Credit costs; dismantling uses the Scrap costs.
The calculation uses the current cost table without Mastery discounts. Each level's cost follows the usual upgrade rounding, and any fractional amount in the final bonus is discarded. Parts of the same rarity and level return the same amount, even if their owners used different discounts.
For example, a Rare +5 part has accumulated standard upgrade costs of 2,375 Credit and 32 Scrap. Selling returns 893 Credit: 300 for its rarity plus a 593 bonus. Dismantling returns 16 Scrap: 8 for its rarity plus an 8 bonus.
The 5,000 Credit value for a Mythic part is its base price. An upgraded part can sell for more. If upgrade costs are rebalanced, returns follow the new cost table. Check the amount shown in the confirmation.
