Any guesses on the stiffness? I'm expecting something between 1,000 and 10,000 lb/deg, if I did it right. Took all the measurements but have yet to calculate the results. Instead of using dumbbells to load the arm I used a bare iron Pinto head that was sitting in the corner of the garage. Pretty much the same result. That thing is 43 lbs! #becauseracecar #racecar #f2000 #scca #greatlakeschampionship #makersgonnamake #makersmovement #drivefreeordie
