control arm stiffness test
 

I have possibly come up with a way to improve the stiffness of the 914 control arm without the weight gain of boxing it. Does anyone have any idea as to how to test an arm to measure the improvement (or lack thereof) in a meaningful way i.e. increased stiffness only matters if its in the direction really counts (what direction is that in this case?). My goal is to test all three permutations (stock, boxed and ???) to see which works best. I promise I will share this info with one and all whether it works or not! Thanks!
