Upgrade performance with vehicle modules

A vehicle upgrade belongs in the right part of your car. ROB RUN uses performance modules that install in different locations: beneath the hood, inside the trunk, or on the underbody, according to the modification. Check the module's intended location before trying to fit it.

This ROB RUN vehicle upgrades guide covers the installation system the developer has actually described. The official car ownership and modification guide confirms that modules improve performance, without publishing a full catalog of stat bonuses or a universal best build.

Prepare your personal vehicle first

The official ownership route starts with acquiring a land plot that includes a house or garage. You can then purchase a personal vehicle and keep its key in your key locker.

Keep that ownership setup separate from getting temporary transport. If you have no active vehicle, you can obtain a free car rental at the nearest Parking Terminal. The free-rental rule does not establish that rental cars share every ownership or modification feature.

If your goal is to build a modified personal car, begin with the property and key requirements. If you only need immediate transport, the rental route may address that need without completing the personal-ownership setup first.

Match the module to its installation location

The installation location depends on the modification. The three locations identified in the official guide are:

  • Under the hood.
  • In the trunk.
  • On the vehicle's underbody.

The guide does not assign a complete list of named modules to those locations. Check the specific modification you have rather than assuming, for example, that every performance part belongs under the hood.

Before purchasing a part, compare its stated effect with what you want from the car and confirm its installation location. This avoids making a decision based on an invented tier list or a promised percentage improvement that the developer has not supplied.

Remember that a trunk is not automatically secure storage

The trunk has a role in the modification system, but other players' vehicle trunks can also be opened with a lockpick bought on the Black Market. The official trunk guide explicitly includes cop cars among the targets.

That is a reason to keep access and security separate when using your vehicle. The available material does not say which installed modules can be removed or stolen, so it would be misleading to extend the trunk-lockpicking rule into a specific module-loss claim.

FAQ

How do vehicle upgrades work?

Performance modules are installed on the vehicle. Their fitting point depends on the modification: hood, trunk, or underbody.

Is every module fitted under the hood?

No. The official guide also identifies the trunk and underbody as installation locations.

What is the best vehicle upgrade?

The available official material does not rank modules or provide measured stat comparisons. Use the effects and requirements displayed for your own available parts.

What do I need to own a car?

The developer's instructions start with a plot containing a house or garage, followed by purchasing a vehicle and keeping its key in your key locker.
