What I changed from the setup and it seems that alot of people are doing this, is if you are running the side-by-side saddle packs like the stock or BMI 350 chassises run light purple springs up front (Pepto Bismal pink springs) and Violets in the rear. The setup he is using works perfectly if you are using the BMI split chassis. Thats all I did was change the springs and the setup works perfectly.
