Because the diameters of the tire to use are different, full size touring chassis and A210SS are different in the feeling in the same gear ratio.  When you refere to the gear ratio of the full size touring car,  Please recommed the following calculation method :

(Tire diameter of Full size touring car/64mm)/(Tire diameter of A210SS/55mm)=1/16
(Best ratio for your touring car)/(1.16)=Similar feeling Ratio.
