20s for the Demon - how low can I go? (big wheel haters don't look)
I haven't looked closely at Denny's k member or control arms enough to know, but one option to make an air bag work "could" be to lower the mount in the LCA. I don't have a good picture on photobucket but I dropped my mount between the two tubes on the LCA which keeps the top of the shockwave from "trying" to squeeze through the upper control arm. Another option "could" be, to pull the lower mount in closer to the chassis, making the shockwave as vertical as possible, while using the shortest shock RideTech has. By pulling the bottom mount in, you still maintain wheel/suspension travel but would want to calculate exactly how much. Can then locate bumpstops to ensure the shocks do not bottom out on compression, though they now have internal bumpstops. RideTech recommends a total of 5" of travel, 3" compression, 2" extension. A final option "could" be, to invert the shockwave and use there external level sensors rather than internal. This "should" keep the convoluted bag below the UCA so just the shock comes through.
In terms of which bag, a double convoluted is necessary up front given the weight of the engine. A rolling sleeve bag is not sufficient. Per RideTech's encouragement, I'm even using a double convoluted bag in back to account for the added weight of my chassis and the IRS center section being fixed to the chassis. Based on estimated weights, it shouldn't be necessary, but RT preferred it to be on the safe side.
This pic isn't the best at demonstrating what I'm talking about by lowering the mount in the LCA, but you can see the shockwave does not come through the UCA.
