Re: fitment question
Provided the front hub fits through the ID of the wheel, they will fit without spacers. You could later add the spacer. I would suggest a 10mm spacer with the hubcentric flange

Re: fitment question
yea i think i would need spacer looking at the cap sizes
73.1 -> 54.1,
73.1-> 56.1,
73.1-> 60.1,
73.1-> 64.1,
73.1-> 66.1,
73.1-> 67.1
i dont know how accurate are the numbers tho look into another source and there saying 68mm but even then still to small
but i expected that
now woundering if i should bother with staggered setup or squared up hmmm
thanks once again for your thoughts //<86>\\
long hard day at work has my math mess up right now

Re: fitment question
If you get hubcentric rings, you need 73.1x70.3. Common size and get the aluminum ones not the plastic ones.

Re: fitment question
yea i know always woundr why they came in plastic
im probably going too have to run spacer like on my 18x10 due to the hub
there hubcentric to hub and wheel pretty cool actually no need to run the little ring
i have 1.25 and 1in spacer laying around which would need those rings
