like I said the spokes of the wheel hit on the arm.
shocks aren't hitting just the arm.
I have the standard rear RDX hubs not the vertical hubs.
I use the narrow hexes and I use 2 deg toe in, no other spacers to space it out.
If I use the wide hexes in the rear I'm past the 190 rule...
its not much but it is too wide to fit in the box...
