Have her watch a bit of this Steve she can see my entry VS hers and maybe why she kept getting loose out of 4, she also seemed to not let the kart track out coming off the corner, almost as if she was too stiff
Could also be shes in the throttle a little too much I found in some instances lifting off just a bit and throttling out from just before the apex of the corner and flat footing the throttle all the way out of the corner and down the straight away
