Hmmm, simple math. The RX7 2nd Gen was a Mazda 944 reincarnate. I owned an '87 RX7. The Car's dims were very close to the 944. The Factory control arms were designed way stronger than the 944 alloy control arms (2X the alloy). So I designed an adapter bracket with at least 2X it's strength. So you do the math. 4X stronger than the 944 alloy arm?
I will post up real world results in about 2 more months for my car with the IRON block 5.3l V8 installed. Believe me I won't go easy on this street menace
and will be using it as a demo for the V8 conversion kit I designed. I will also be running modified EARLY STRUTS, LATE SPINDLES that I Cryo-treated and the LEXUS 4-POT MONOBLOCK calipers on my set-up. I will ask the 2 other users to post no-bull reviews also. One is still putting in his V8 and can't say when he'll be done.
As for testing. I will put these arms up against the stock stuff in a shear test anytime and even give a 50% handicap on load bearing for the factory arms.
