Wanted to let people know there is a mounting issue when using Fox spindles, Lincoln 5 lug rotors and the F5 17" x 9" Vintage Halibrand Replica Wheels.
F5 knows of this issue.
When mounting the 17" x 9" Vintage Halibrand Replica Wheels with Fox spindles, Lincoln 5 lug rotors and lug nut cover hardware the wheel sits approximately 3/8"-1/4" from the rotor mounting face when using the
non machined wheel (pictured below).

To try and fix this, the manufacture has
machined the centerbore deeper (more towards the outside), but this may still not help some people (pictured below).

I have had both wheels (machined and non machined) and still was not able to get either of them to mount correctly without some work.
For me, to mount the
machined wheel I would have to use a 1/8" wheel spacer, but with this combination the thread adapter would stick out farther compared to the rear wheel. I did not go with this option.
To mount the
non machined wheel I would have to use a 1/4" spacer and change the studs on the rotor so there would be enough thread engagement.
I did not go with this option either.
Instead I use a 5mm spacer (could of used a 1/8" spacer) with the
non machined wheel and machine the thread adapter to clear the wheel bearing dust cap (example below) to get the wheel to mount correctly and the thread adapter to be at the correct orientation matching the rear wheel.
Hope this helps someone with their build.
