Z struts have a different stub axle angle. In the Z they get the camber right by setting the towers closer together.
They give lots of positive camber using them in stock strut mounts.
I havent encountered any Z struts with a wider bolt spacing onto the steering arm

L18-B110 do you know which model uses a wider bolt spacing?
When it comes to brakes on stanza struts the cheapest and most effective bolt up brake conversion is the 270mm 240K disc with sumitomo 2 spot calipers. This combination can be used with 13" rims
