That's a good point on the bumper shocks. Mine is no longer a shock. While I agree our frames move around, they are strengthened alot when bolted to a body with poly bushings. Even if they are not that strong. They do not need to be way at the back of the car behind the rear suspension. The suspension area being solid is good enough for me. Look at the beef between the 2 rear tires. As you can tell from my bumper shocks. Weight is a bit of concern so bracing the entire car will be considered with caution. I want it strong but not at the expense of extra weight.
The road time on the torque arm set up is zero. The car is at the build stage. The rear is a 12 bolt center for an F body with G body ends from Moser Engineering. UMI lower control arms with roto joints. No upper arms and a long F body style torque arm.
At this point, not even sure if a my original GN bar will fit since the stock arms are thicker which would make my arms mounting surface further away. Plus as mentioned flat onto round does give me confidence in a good connection. The F body sway will be considered scoti, thanks.
