Performance Parts

Performance Parts featured in Need for Speed: Most Wanted are utilised to improve the top speed, acceleration and handling of a car. The Engine, Transmission, Suspension, Nitrous, Tyres, Brakes and Turbo Charger or Supercharger of a car can be upgraded.

Each performance part category is also divided into upgrade packages. Each package offers greater performance gains for a car but some vehicles can not be equipped with certain lower level packages. The upgraded levels are Race, Pro, Super Pro and Ultimate.

Junkman parts permanently raise a performance aspect and can be stacked with any upgrade package. They can be unlocked by selecting the "Unique Performance Upgrade" marker upon defeating a Blacklist racer. They can be unlocked for usage in My Cars by completing the Burger King Challenge event in the Challenge Series.

Players can make individual adjustments to various aspects of their car's performance by accessing the Performance Tuning window from the pause menu during freeroam gameplay.

Trivia

Development - Main article: Need for Speed: Most Wanted/Development.

• In the game files of Need for Speed: Most Wanted, two unused performance packages - Street and Super Street - can be found.
• Although the description for Unique Performance Upgrade markers mentions nitrous as a possible reward, none of the Blacklist members offer it as a reward.
• To account for the Mazda RX-7 and Mazda RX-8 using a rotary engine instead of a piston engine, the Pro and Ultimate packages for engine upgrades mention "Lightweight Rotors" and "Carbon Apex Seals" instead of "Forged Pistons" and "Racing Pistons" respectively.
