Update: Finished my brake upgrade a few months ago.
I was running short on time and ended up having a local speed shop do it.
Short version:
It was a hell of a lot easier than I expected it to be and none of the OEM piping I was planning on using was necessary.
1.They installed rear dust shields, and Z1 SS lines (non-premium)
2. Calipers went on without a hassle. They did use new bolts on the front caliper mounts. Not sure if that was a 100% necessary.
3. No issues with any of the banjo bolts like I have heard so many stories about. Been under the car a few times since the install and nothing is leaking.
4. No issues with extra slack in the Z1 lines.
Took some other pics of the SS lines if anyone needs some visuals send me a PM
