You'll also need to either get the shorter banjo bolts from Z1 or got to SS lines. I used the shorter banjo bolts just to save some money for now, $20 compared to $100.

When you put them on you'll need to either trim the dust shields or switch them for the proper shields. I trimmed them because the shields are a pain to get off.

I also spent some extra time before hand to paint the calipers.
