Hmm. I can see what you were thinking when you designed the front mount. I am wondering how effective it will be to control axle wrap. As loose as it is I really doubt it will have much of a controlling effect on pinion lift at launch.
It won't cause any bushing bind in the leaf springs because it will just saw back and forth on the shackle during jounce and rebound.
I will be very interested to hear how it works out. I would really like to see a go-pro vid of it in action.
Keep us in the loop on this please.
