Like to make one more point, the closer the ladder bar-4-link-spring to the tire in conjunction with the smallest offset rim, the less chance of bending. Think of a pry bar trying to lift a heavy object, the closer the fulcrum is to the object the more the bar will bend, closer to you hand the more effort you will need to bend that same bar.The tire is moving forward and pulling 3000 lbs or more with it and once it gets past the strength of that tube it will bend something hence it will have to be braced. That's why we're seeing the 4-links-ladders in the wheel well outside the frame next to the tire, more stable too. Don't hook the brace to that cover use a tube with solid heims(just like a 4-like bar with flats) between the braces for suspension, just drop the bar and everything's in the clear. No more complicated or "heavy" 10 lbs at the most, than anything else on the RACE CAR. I'll try to make a drawing to simplify.
