S13 yes, I just lightly filed the burs on my sedans stud holes. The run 180 deg the wrong way so when set for neg camber in a 1200 that woul be the setting for max pos camber in a s13. Mounted mine so it gave some castor adjustment too.

If you want more meg camber use stanza lower ball joints too- gives you an extra deg meg camber

yes piggy and I running the Honda kits, they are 51mm from memory so perfect for stanza struts etc.
