# How to Configure Dynamic Track Grip in Assetto Corsa

> Learn how to configure dynamic track rubbering to simulate realistic grip evolution during a race session. Balance initial traction and lap-by-lap progression.

## Evolution of the Track Surface

One of the most immersive features in Assetto Corsa is dynamic track grip. As vehicles complete laps, rubber is laid down on the tarmac, increasing the available traction for all drivers. This evolution requires drivers to adapt their braking points and cornering speeds as the session progresses, just like in a professional motorsport event.

## Configuration Settings

You can fine-tune the grip evolution within your `server_cfg.ini` file under the `[DYNAMIC_TRACK]` header.

<Steps>
  <Step title="Access the Config File">
    Log in to your [Game Panel](https://panel.freakhosting.com), go to the **Files** tab, and open `server_cfg.ini`.
  </Step>

  <Step title="Set Initial Grip">
    **SESSION\_START:** Defines the percentage of traction available at the start of the session.

    * *Example:* `89` results in a "Green" track with low initial grip.
  </Step>

  <Step title="Configure Grip Carryover">
    **SESSION\_TRANSFER:** The percentage of rubber remaining on the track when transitioning between sessions (e.g., from Qualifying to Race).
  </Step>

  <Step title="Define Progression Speed">
    **LAP\_GAIN:** The amount of percentage grip added per car completion of a lap.

    * *Example:* `1` means the track gains 1% grip every time a car finishes a lap.
  </Step>
</Steps>

## Impact on Race Strategy

The way you configure these settings defines the tactical landscape of your server.

<Tabs>
  <Tab title="Green Track (Low Grip)">
    Setting a low `SESSION_START` (e.g., 85-90%) creates a "Green" track. The surface will be at its grippiest in the final minutes of the session, forcing drivers to time their fastest qualifying laps perfectly.
  </Tab>

  <Tab title="Fast Track (High Grip)">
    Setting `SESSION_START` to 98% or higher provides a "fast" track immediately. This is ideal for casual drift sessions or short sprint races where you want drivers to push from the first corner.
  </Tab>
</Tabs>

<Tip>
  ### Pro Tip: Randomness

  You can also use the `RANDOMNESS` parameter to simulate unpredictable weather conditions or track cleaning, which adds a layer of uncertainty to the available grip.
