The RX7 alloy arms are more than 2X the thickness of the 944 ally arms in the ribbing and I designed the bracket 2X as thick as the RX7 B-joint bracket. I have never seen nor heard of an EARLY 944 replaceable B-joint breaking, but have seen the alloy 944 B-joints pop right out the top of their sockets. They have PLASTIC bushings in them. The alloy of the 944 is porous and if you smack the sh%#& out of it with a hammer it cracks. I did smack the area of a spare RX7 arm and it SMUDGED and determined the casting process of the Japs alloy is far superior. I have machined many metals over the years and alloy casting is a science that the Japs have perfected. VW/Audi alloys are not as compact in the casing (porous)

I did choose the Cold-rolled steel that was annealed. Because un-annealed steel has a slight brittle factor to the metal matrix.
