Adjust the distance between the two ballends on the steering bridge with this insert steering bridge system! What this achieves is different ackermann settings and adjusts how much steering angle difference you can achieve between the outside and inside tires when you turn.

By using a larger distance (bigger number), the outside wheel will turn more and create a more aggressive feeling. The 8.0mm insert will make the wheels turn at a more equal angle and will result in a more stable driving car.
