20mm spacers + eibach springs won't rub right?

I was asking myself that same question....and or Ichiba for that matter. I am looking at getting the H&R DRM or Ichiba Version II 20mm all around (direct bolt on). From what it looks like is that the Z1 spacers are not type 2 or direct bolt on. Instead they are the stud replacement style. I am guessing it is preference on which style you want.

But I am also curious about the difference between H&R vs Z1....as well as direct bolt on or stud replacement style (pros/cons).
