Before I called this morning, I rethought my SB motion ration concern, being the SB has a relatively short arm acting on the LCA, it may not be much of a concern, it's all about the numbers anyway.
Take everything here with a grain of salt in that its still a work in progress it seems.
SB is maybe 1.375"D hollow, Wheel BC is 4.5" Not sure if hubs will allow for 14mm studs, needs large dia wheels to fit tall spindles, Not sure if hub/bearing packages are the SKF Tracker series (the HP vette bearings), the robustness of the upper coil over mount has been rethought I am told, it might come powder coated or bare, they are taking names/refundable deposits for orders, will gather wheel combos/widths, they have not yet test fitted it to an E body.

I am on the list.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
