The next stage from applying full steering lock, is to move your body weight around the kart so you can gain extra grip when required.
Considering that in some cases, your body weight can make up 40% of the total kart weight, it’s a vital factor that can drastically change the handling characteristics when used correctly. Typically to gain more grip, which is always helpful in the wet weather, drivers will shift their body weight towards the outside front tyre. So when steering a left hand turn, the driver will push their body towards the right hand front tyre, while steering full lock. Then the opposite would occur when turning a right hand corner, the driver would shift their weight towards the front left tyre.
