Bob thanks for the drawings - I ordered the Wilwood hubs and we started fitting the front this morning. They are very nice pieces. They shift the Trigo wheels in board .100. Since we are going to use 4.5 backspace, this should not be a problem.
We are just touching the caliper adapter so we will need to mill about .100 off the hub at the hub to adapter mounting surface. I looked at your drawing and that is what seems to be indicated so onward we go.
I ordered up some steel wheels to check everything.
Wilwood tech was not at all concerned with strength or application. I was able to get drilled bolts for safety wire for the rotor to adapter. We will have to drill our own for hub to adapter.
Running a heavier GT 48 rotor we still get 15lb of un-sprung reduction.
Will need to mill hub mounting surface .100 which will drop adapter down for clearance with brake caliper adapter.
