Soft configuration: 

Use the fixation point close to the rocker axle. For a 
given ARB travel the WHEEL must travel more 
compared with the STIFF SETTING 

Stiff configuration: 

Use the fixation point further away from the rocker 
axle for a given ARB travel the WHEEL will travel less 
compared with the SOFT SETTING 
  

Configuración blanda: 

Usar el punto de fijación cercano al eje del balancín. 
Para un desplazamiento determinado de la ARB, la 
RUEDA ha de desplazarse más que en la 
configuración RÍGIDA. 

Configuración rígida: 

Usar el punto de fijación más lejado del eje del 
balancín. Para un desplazamiento determinado de la 
ARB, la RUEDA ha de desplazarse menos que en la 
configuración RÍGIDA. 
 

Front ARB values 
  

Valores barra (ARB) delantera 
  

The values shown below are in kg/mm [daN/mm] at 
one end of the blade while the other end is locked. 
 
The values below are measured on the ARB isolated 
from the car. You may use the Motionat ground Ratio 
to calculate the ARB stiffness. 
 
On various ARBs we suggest not to use the 115mm 
blade. 
  

Los valores que se muestran a continuación son en 
kg / mm [daN / mm] en un extremo de la cuchilla, 
mientras que el otro extremo está bloqueado. 
 
Los valores a continuación se miden con la ARB 
(barra) desmontada del coche. Se puede utilizar la 
relación de movimiento para calcular la rigidez de la 
barra (ARB) 
 
En varias barras le sugerimos no utilizar la cuchilla 
de 115mm
