For those interested, I was able to install extended wheel studs from Kyo-Ei SBLC. Was able to get thread engagement of at least 9.5 turns. I used 112 mm to 95.1 mm hub rings but that precludes using center caps due to push through design.
There are no push in center caps available for these wheels. Next step is to use 106 mm to 95.1 mm hub rings to accommodate the center caps. I was running Method MR305 wheels previously and there were slight vibrations through the steering column at speeds above 70 mph. The hub rings have remedied this issue so I'll be sticking with rings going forward.
