#3R (same as 1 rebound / 3 compression) #4/3 (4 rebound / 3 compression)
Tightens chassis up throughout the corner to create more side-bite than #3 valving. Frees the chassis up on corner entry and turns better on corner exit than #3 valving. (For flat or slow tracks.)
   
  #3/4 (3 rebound / 4 compression)
  Tightens the chassis slightly more throughout the corner than #3 valving. (Great for high banked tracks.)
