TAKE IT
FURTHER.

Your car does not become fully upgraded all at once. You need to learn it, drive it and develop it.

Spoiler-free guide. Here you will only find what you need to understand the system. Locations, missions, exact rewards, secrets and special conditions are deliberately left for you to discover in game.
01 / TWO DIRECTIONS

STYLE AND PERFORMANCE

Customization is split into two main areas. visual modifications change the car's appearance; performance upgrades affect the vehicle's behavior and capabilities.

LOOK

STYLE

Bodywork, colors, wheels and visual details. Some options depend on vehicle progression.

GUIDE

PERFORMANCE

Upgrades that change how the car accelerates, brakes and behaves on the road.

02 / UNLOCKS

MONEY ALONE IS NOT ENOUGH

Some parts require the individual vehicle to have gained enough experience. That is one reason why actually driving the car matters as much as buying it.

Deliberately omitted: we do not publish a complete table of every level and every part.
03 / DYNO LAB

MEASURE BEFORE YOU PUSH FURTHER

At the Dyno Lab you can put your car on the dyno and get a clear view of its performance: power, torque and estimated top speed, together with the delivery curve. It is the easiest way to understand how a setup changes the car.

The system also keeps a history of your runs, so you can compare different configurations and see how each preparation changes the overall result.

Street Racer Dyno Lab performance test.
The dyno gives you a compact performance readout and lets you compare different runs of the same car.

Beyond the standard upgrades, the Dyno Lab also offers additional performance modifications. They act as another layer of preparation and follow their own progression path.

This guide intentionally does not reveal the full tree, individual components or exact effects: experiment, test the car and use the dyno to understand which direction suits it best.

Dyno Tuning adds another performance path on top of the standard upgrade system, without replacing it.
Comparison is what matters: run the car before and after a preparation to see the difference clearly.
04 / MANUAL GEARBOX

MORE CONTROL, MORE RESPONSIBILITY

If you choose manual transmission, you can have a more direct and technical driving experience. More advanced configurations require greater attention to the clutch and engine RPM.

05 / NITRO

IT IS NOT JUST A BUTTON

Nitrous, when installed, has a limited reserve. Street Racer rewards active driving: certain actions behind the wheel can help recover charge while you keep driving.

Discover it by playing: we do not list every action that recharges nitrous or how much each one gives. Watch the gauge and experiment.
