Every vehicle part in Star Wars Galactic Racer
Vehicle parts are the mods you install to change how a vehicle performs in Star Wars Galactic Racer, and there are 318 of them. They come in five rarities: 40 Common, 91 Rare, 70 Epic, 57 Legendary and a single Experimental.
Most run through a family of four tiers, so Faster Attachments I through IV are the same effect at Common, Rare, Epic and Legendary strength. Prices follow the rarity: 2,000 credits for Common, 2,500 for Rare, 3,000 for Epic and 4,000 for Legendary.
Faults in Star Wars Galactic Racer
Fifty-nine of the vehicle parts are Faults. They carry a drawback rather than a benefit, and they arrive on a vehicle when you buy a discounted faulty upgrade or when a sponsor or scenario forces one on you. A Fault costs 250 credits to clear in the campaign.
Reading a Fault before you accept the discount matters, because some of them only cost you a little heat while others apply Corroded or System Malfunction the moment you use an ability.
Vehicle parts are not body parts
The body parts that make up how a vehicle looks are a separate thing in Star Wars Galactic Racer. Those are cosmetic, they cost Kit Points rather than credits, and they live on their own page. A vehicle part changes how the machine behaves; a body part changes how it looks.
