# suspensionCompression

The coefficient that limits the speed of the suspension returning to its rest length when compressed.

## Declaration

```swift
var suspensionCompression: CGFloat { get set }
```

## Discussion

Discussion The default suspension coefficient is 4.4. Lower values cause the wheel to return to its natural position more quickly.
