NFSU1 Icon Performance Parts

Performance Parts in Need for Speed: Underground are components equipped to cars to improve their performance in events.

Performance part packages are unlocked for purchase as the player progresses through Underground Mode and beats specific events, usually unlocked by completing tournaments.

Each package is categorised as Stock, Street (Level 1), Pro (Level 2), Extreme (Level 3), and Unique. The latter offers the highest performance increase.

Players may also select between various brands for performance packages. Although each brand package does not differ in performance between each other, selecting a brand package will unlock associated brand decals.
