Schumacher have introduced two new option parts in the form of a rear roll centre conversion and king pins for the Atom. First up are the rear roll centre conversion kit that provide an adjustable rear roll centre. This gives an ability to adjust the rear roll centre from a very low kit standard position. Raised roll centre gives a more responsive lively car, ideal in high traction conditions. Kit lower roll centre position gives more rear traction. Next up is a pair of king pin polished, it provide for low coefficient of friction and improve smoother suspension action.
