Well consider, 11g is a bit tough to dimple die, and IMO the housing is resisting two primary forces in the back brace area, torsion/twist, not sure how much dimple die would add to resist that, and that calculation is above my pay grade, and bending, from the forward thrust forces, which bends the center span of the housing rearward, or the opposite of the tire side of the spring pad(?) which is bending forward, meaning the back brace is mainly under tension, and adding dimple dies adds little stiffness/strength. Now if the brace was in compression, I agree, your suggestion would likely be beneficial.
