Moved into the next step of stiffening the chassis by adding the rear upper strut brace. Seen some of them manufactured by Wiechers mostly. They all attach to the inner side of "wheel arch" though. Decided to make one on my own rather. I'm not a welder nor a mechanic or anything similar by profession so please apologize the look of my joints
As you can see from the pictures below it's rather simple design connecting upper mounts of rear shocks. As they are actually forming the A shape and to make it even more stiff had to make it adjustable by adding opposite thread rod. It made it a bit heavier however saved the weight using extra strong thin sidewall steel tubes. All together it weights 1340 g before powder coating.
Lower brace will follow later. It will be either a rather simple Unicorse design or maybe even the stiffer Ultra Racing one.
