IRS design problem

This hub carrier isn't over engineered as you mention, and the mounting is all important, but two things here for general use and a few laps, the standard rear brakes should be okay, if not I will uprate them, but I have run some quick laps on no better rear brakes than these, the front brakes are a different story, I have circuit use 48 fin curved vein rotors with large Billet calipers!
The Cobra is much lighter than a T/Bird or a Lincoln, but obviously there is a lot more power and maybe G Forces in the Cobra, so how strong does the Hub carrier need to be?

I am now modifying my bottom arm for much better mounting, as similar to JBL, the top arm is questionable whether its okay or not I would imagine that with the better bushing and the single "wide" bearing strut it has! - that it would move a lot less than rubber bushes, if I am concerned about it I could run a radius arm back on to the upper rear chassis rail for horizontal loadings!

I guess some people think as my supplier does that the upper hub carrier bush is for camber or in and out forces, but I think the upper bush takes fore and aft plus some rotational loads!

Thanks Ant
