Ive done the calculation for the required stiffness of the ARB, and for a motion ratio of 1.6 i got the stiffness to be around 600Nm/deg. Just wondering,does the arb that is going to be build has the same stiffness? Im just wondering that the effect were if the design stiffness is bigger than the required arb rate. thanks

That end of the car will be 'slidey.' You might pick up an inside wheel. The design judges will look at you funny if you tell them this.

Is that your overall ARB stiffness or your Required ARB Roll Rate? 600Nm/deg seems a extremely excessive and id say you have mucked up a calc somewhere

thats the overall arb stifness from calculation. its because of the high motion ratio, with a motion ratio of 1:1, the rate is just a mere 367Nm/deg.
