One thing to remember - whats the most common question on this forum.....'Will these fit....'
so maybe some way to counter that problem - I.e. If you could get examples of each wheel on a Zed with specs - i.e. 20mm Spacer, x*Camber, Rolled Arches.
I know it's a bit OTT but I think it'd be a good sales tactic considering people spend days waiting to find out if the wheels they want will fit before they purchase, least this way they can just simply see it in the details and click buy
