The red car needs the battery moved back more over the rear tires to hemp its weight balance. The reason why its having such a hard time is because it has to much steering traction and not enough rear grip because of the weight balance. If you notice in the GTB manual there are multiple holes in the chassis for the battery tray to move forward or backward but on the car they have chosen not to drill the different holes so the stock default setup of the car has this over steer setup which imo sucks
