I've put about 500 (hard) miles on the setup and have been inspecting everything often. No issues yet... My car is making about 350whp/tq currently.

If the spring plates were channeling 70-80% of the forward & rearward thrust, the rubber bushings therein would fail along the 9 o'clock - 3 o'clock plane. Counter to your 'basic math', they fail at 6 o'clock from the weight of the vehicle levering against the TBs et all.
My smooth brain managed to figure that out with zero math required, just a basic understanding of what every car on this board has experienced at some point in the last 50 years.
I am not your enemy. I am just trying to understand how these modifications are being completed in a safe, reliable way without a full cage.
