Steering

These upgrades do not effect Performance Points (PP) in any way. Not necessarily a vital upgrade but the Steering Angle Adapter is worth testing. You may find a higher steering ratio gives a quicker initial response to steering inputs through the wheel, however this may reduce the vehicle's controllability at higher speeds.

A Four-Wheel Steering Controller will allow you to control the rate the rear wheels will turn into the corner. This will make the car more nimble by reducing the tracking effect all vehicles have without rear wheel steering.
