# Upgrades

The Mod Shop can offer you many upgrades to customise your vehicle for racing purposes, or if you'd like to drive further for much longer.

***

## How to upgrade

You'll need to drive your vehicle into the Mod Shop located at **2000x 1230z**. Once you've driven in, simply click the 'Install Upgrades' chat button and browse the menu. When you finished upgrading, press SHIFT to exit with your vehicle.

## What do upgrades do?

### Engine

On an engine upgrade, you'll notice 3-4 attributes which each change the way you drive. So, what do these do?

* **Accelerator Chance** - Every 10 seconds, a Random Number Generator decides if you can accelerate; the higher the chance, the more often you'll be able to accelerate.
* **Fuel Usage** - As you can imagine, fuel usage indicates how much fuel you use when the vehicle is moving. A negative fuel usage (e.g. -10%) means you'll use more fuel, whereas a positive one (e.g. +10%) means you'll use less fuel.
* **Reverse Speed** - This increases the speed at which you can reverse your vehicle.
* **Max Speed** - This increases the overall speed at which you can drive your vehicle.

### Fuel Tank

The only attribute fuel tanks offer is **Tank Capacity**, it'll display the exact capacity you'll receive upon upgrading, e.g. 75L.

## Brakes

On a brake upgrade, you'll find 3 attributes which change the way your car brakes.

* **Brake Friction** - This increases the speed at which your car brakes, as a stock brake will take a second to come to a full stop with your **SPACE** key.
* **Friction** - Friction will increase how quickly your car can take off.
* **Turn Speed** - This will increase the speed at which you turn with **A** and **D** keys.
