Somehow my car has survived without boxed arms....for 5-6 years or AX on a very rough venue. 4 lbs each of unsprung weight goes against my grain....unless I can see a need.
I took 2-3 lbs out of my swingarms, it fact
I have well above average chassis stiffness, tire, power, springs, with pratically no rubber in the suspension....rear shock tower rubber only. No " chassis stiffening kits", tho.
The reason I bring up chassis stiffness is because it is intertwined with the suspension. The more chassis stiffness, the more load is absrobed by the suspension bits.....the same with the lack of rubber in the suspension. The suspension is supposed to do the work, not the chassis.
The metal bits in the suspension hold the alignment.
This bit of info comes from a guy out flogging his car, not just talking about theory.
I've done a bit more chassis work this winter to improve it's
stiffness. The front & rear shock towers are tied into the cage.
