Longer drive shafts (52mm) make the car easier to drive because they
give more traction and better stability, mainly in chicanes. However, the
car will understeer more than with shorter (50mm) shafts which give a
lot of steering and impart aggression to the car. You may also combine
different lengths of shafts in front and rear (for example, using long shafts
in the rear and short shafts in the front) depending on track conditions.
Both left & right shafts should ALWAYS be the same length at one end of
the car (front or rear).
52mm shafts are recommended for carpet and big asphalt tracks
50mm shafts are recommended for small-medium tight asphalt tracks
