I just realised something that might help you out!
It might be the ARB hitting the DS if its right hand lock your hitting on?
Or can you see the tyre hitting the arch?
Yeah, you can see the rubbing mark on the inner arch. And thinking about it, i was getting the plastic adaptor, spigot ring I think, confused with a spacer, so i have NO spacer on. And as KEI do tend to make wider wheels, the rubbing could just be a result of the lowering
So the passenger side adjustment is my next move, to see if that rubs when its the same height as the drivers side.
The saga continues........
